Why planes still have no smoking signs

Have you ever wondered why planes still have dozens of no smoking signs inside an aircraft, even 30 years after a worldwide ban was implemented? A travel expert has answered this age-old question, just weeks after the US Federal Aviation Administration (FAA) got rid of the off switch for no smoking signs. This means that for all American planes across every US airline, the no smoking signs stay lit throughout the entire time you’re on board, which includes taxing, takeoff, cruising and landing. While it would seem that no smoking signs onboard planes are no longer needed nowadays, they are actually very much needed. “While no smoking signs may seem like an old and outdated practice, they are still a necessity for a few different reasons,” RVshare travel expert Maddi Bourgerie told <a href="https://www.thrillist.com/news/nation/planes-no-smoking-signs-why-expert">Thrillist.</a> Firstly, it’s down to public health and safety, as Ms Bourgerie said, “There are aviation regulations in place that require airlines to maintain a no-smoking policy, which is largely due to the flammability of materials in the cabin.” She added, “the signs reinforce a smoke-free environment for all passengers and crew,” with second-hand smoke being dangerous to those around you in an enclosed space. Ms Bourgerie also explained that having the signs gives the airline some protection from potential lawsuits, with the signs acting as a safety net if a smoking-related incident occurs on board. The travel expert also pointed to a less obvious reason for keeping the no smoking signs, explaining, “Many procedures and protocols in aviation are maintained for consistency and familiarity.” “And the no smoking sign has become a standard part of the in-flight experience.” Image credits: Shutterstock

Tourism hotspot in Italy attracts attention for selling strange souvenir

Italy’s picturesque region of Lake Como has started selling a unique souvenir, making many people raise their eyebrows. The north Italian tourist hotspot has long been known for being the backdrop of many Hollywood films, while also hosting countless celebrity weddings, with many famous faces owning houses in the region. For those travelling to the stunning Lake Como and wanting to purchase a souvenir to remind them of their travels, you can now forgo the classic keyring or magnet for a more unique souvenir item. Communications company ItalyComunica says it has bottled the very air of Italy’s picturesque Lake Como and is selling these cans for €9.90 ($16 AUD) apiece. Each can is said to contain 400 millilitres of “100% authentic air” collected from Lake Como, with the website stating buyers can “Open it whenever you need a moment of escape, tranquillity, or simply beauty.” In an attempt to capitalise on the ever-growing visitor numbers, marketing specialist Davide Abagnale originally created the e-commerce site to sell dedicated Lake Como posters, before delving into the world of the unique souvenirs. His latest initiative of selling canned air aims to “create a souvenir that could be easily transported in a suitcase for tourists” and “something original, fun and even provocative.” Abagnale told <a href="https://edition.cnn.com/2024/11/04/travel/lake-como-air-cans-on-sale-intl-scli/index.html">CNN</a>, “It’s not a product, it’s a tangible memory that you carry in your heart,” adding that once tourists are home and have opened the can, they can repurpose it as a souvenir pen holder or plant holder. Not everyone was first onboard with the idea, as Como mayor Alessandro Rapinese said it wouldn’t be his first idea for tourists, and would prefer they take home other souvenirs, like the silk scarves the area is known for. “It’s a novel idea, but not for everyone,” he told CNN. “But as mayor of one of Italy’s most beautiful cities, if someone wants to take some of their air home, that’s fine as long as they also take beautiful memories of this area.” Image credits: ItalyComunica/CNN/Shutterstock

Drunk couple forces emergency landing after mid-air meltdown

A Ryanair flight to Ibiza had to be diverted after a drunk couple allegedly assaulted cabin crew and other passengers. The plane, carrying holiday-makers from Manchester to Ibiza had to make an emergency landing in Toulouse, where police hauled the intoxicated passengers off the plane. A British traveller on the flight, who asked to remain anonymous, recalled the man "swigging duty free vodka" on the first hour of the flight, before he started arguing with a male cabin crew member and punched him in the face. As they tried to restrain him, the intoxicated man assaulted another passenger and spat at a woman, hurling verbal abuse at her. “He was kicking off with everyone, he was out of control,” the witness said. Flight attendants reportedly warned him that the flight would have to be diverted if he didn't calm down, but he replied: “I don’t give a f***.” The altercation lasted for about 40 minutes until Flight FR2626 had to land in Toulouse, and 12 police officers took him away in custody. Video of the attack showed the man shouting and swearing at the police, before assaulting another traveller as he was being escorted off the flight. After he left the plane, his partner started harassing another traveller, hitting him and calling him a "paedo". In another video, police were filmed physically restraining the woman, before removing her from the plane. The flight spent just over an hour and a half on the tarmac at the Toulouse-Blagnac Airport before continuing its journey to Ibiza. Just last week Ryanair chief executive Michael O’Leary called for flyers to be limited to two drinks at airports to crack down on disorderly behaviour on flights. “We don’t want to begrudge people having a drink," he said. “But we don’t allow people to drink-drive, yet we keep putting them up in aircraft at 33,000ft. “In the old days, people who drank too much would eventually fall over or fall asleep. But now those passengers are also on tablets and powder. “It’s the mix. You get much more aggressive behaviour that becomes very difficult to manage.” The airline has started carrying out hand luggage checks to stop passengers on flights to Ibiza and the Greek islands from smuggling duty-free alcohol on-board. A Ryanair spokesperson has apologised for the incident saying: “This flight from Manchester to Ibiza diverted to Toulouse after a small group of passengers became disruptive in-flight." “The crew called ahead for police assistance, who met the aircraft upon landing at Toulouse and offloaded two passengers before this flight continued to Ibiza. “We sincerely apologise to passengers for any inconvenience caused as a result of these unruly passengers’ behaviour, which was beyond Ryanair’s control. This is now a matter for local police.” Image: news.com.au

Strangers lock toddler in plane bathroom to stop her tantrums

The video of a controversial incident on a plane has caused outrage, as two women reprimanded a screaming toddler by locking her in the bathroom on the aircraft. On a Juneyao Airlines flight from Guiyang to Shanghai, China, in late August, a one-year-old child, who was travelling with her grandparents, reportedly sobbed non-stop during the nearly three-hour flight according to the <a href="https://nypost.com/2024/08/30/lifestyle/strangers-lock-crying-tot-in-airplane-bathroom-to-educate-her/" target="_blank" rel="noopener">NY Post</a>. After being fed up with the toddler's tantrum, two women who were strangers to the family reportedly transported her to the bathroom to “educate her.” Shockingly, the child’s grandmother consented to the treatment. The punitive pair then shared the video of this alleged “potty training” on Douyin, China’s version of TikTok. In the clip, the women can be seen seated in the locked lavatory with the screaming infant, as one of the women is heard saying, “If you stop crying, aunty will take you back to grandma” and “We won’t let you out unless you stop crying.” As the girl stopped crying, the woman filming the video picked her up and told her: “If you make any noise again, we’ll come back (to the bathroom).” One of the women was initially proud of her cruel and unusual-seeming form of discipline, as she wrote that the tantrum was so disruptive that “many passengers were using tissues to block their ears” while others “had moved to the back of the plane to escape the noise.” According to a statement from the airline, the little girl's mother, who was not travelling with them, reportedly sympathised with the self-appointed aeroplane posse’s behaviour. Since the video went viral, and was subsequently deleted, Juneyao Airlines’ reps have since condemned the pairs’ actions and apologised for the incident and “oversight of the crew”. Despite the video being wiped from the social media site, many were quick to slam the behaviour of the women, saying their discipline was completely unacceptable. “Adults in their 30s can have emotional breakdowns, but people don’t allow toddlers to have theirs,” one person commented, Another wrote, “The grandmother and the two aunts should be sued, and social services should intervene. If there are parents like this, children will suffer in the future.” “When will these people understand that babies have the right to cry and the right to travel, they are part of society, and so are babies!!!!!!!” declared a third.

Woman “bullied” on plane over budget seating trick

A young woman has recalled a flight from hell when she was “bullied” by a couple who were trying to utilise a seating hack that went viral on TikTok. The solo traveller took to Reddit to recount the story and ask social media users if she was in the wrong for her action. The woman began by saying she usually pays more to select her plane seat ahead of time, but a medical emergency on another plane had her waiting on standby and left with no option other than to sit in a middle seat. When she was finally able to board, she was greeted by a couple who had purchased both the window and aisle seats in a bid to have more space, utilising a travel “trick” that has been popular on TikTok. The method, which has been dubbed the 'poor man's business class', usually leaves travellers with an empty middle seat and more space, and few travellers opt to pick a middle seat. “When I got to my row the man and woman were chatting and sharing a snack... it was obvious they were together. I mentioned to the man that I'm in the middle, and he got up to let me in,” the unsuspecting traveller wrote on Reddit. “I asked them if they would prefer to sit together, I said I was totally okay with that. The woman reacted rudely to this and said ‘you're not supposed to be sitting here anyway’.” After noticing how the plane was full, she offered to show the pair her new ticket with the correct seat number on it. “She flicked her hand at my ticket and made a disgusted sound. I offered again if they wanted to sit together to which she didn't reply, her partner said it's okay and... made some small talk,” she continued. The man’s girlfriend then interrupted their conversation to ask,”'Did you use one of those third party websites to book your flight? It's so frustrating when people cheap out to inconvenience others.” The American woman explained that she had booked her flight directly and she had been placed on standby like everyone else and didn't choose the middle seat - she was assigned it. She then tried to keep the peace by refusing to engage with the furious woman. “I was so done with her attitude, I put my headphones on and attempted to do my own thing,” she explained. But the “entitled” girlfriend wasn't letting it go, as the woman explained, “This woman kept reaching over me and tapping her partner and trying to talk to him in a way that was super intrusive.” “I could tell even her partner was trying to engage her less so that she would hopefully stop, but she didn't.” “I think they tried to pull that tactic where they don't sit together on purpose...hoping no one will sit between them. But on full flights it doesn't work. And even so - it's not the other person's fault.” The traveller's post was met with hundreds of comments slamming the girlfriend’s behaviour, as one person wrote, “It's like a toddler having a tantrum.” “She was disappointed and a total a**hole. Gross entitled people,” another added. Another person applauded the traveller’s level-headed behaviour, writing, “Wow! You are my hero for keeping it classy - I’m afraid I would not have been as kind as you.” Image credits: Shutterstock

Flight cancelled after crew member loses it at passenger

An Air Canada flight heading from Morocco to Montreal was cancelled on Friday after a flight attendant lost it at a passenger who reportedly requested a blanket. Viral footage of the incident showed a female flight attendant yelling: “You will behave or we will get off!” at a female passenger. “I’ll tell the captain right away. Yes or no?” When a passenger asked the flight attendant to call the captain, she refused and said: “I don’t want no bullying against my crew”.

Horrifying moment wheel falls off plane during take-off

Video footage has captured the horrifying moment a wheel fell off a United Airlines Boeing plane just moments after take off on Monday morning. The video captured by RadarBox shows the tire coming loose from the aircraft's undercarriage and plummeting to the ground seconds after take off. The airline confirmed that a wheel fell off the plane as the flight departed Los Angeles International airport en route to Denver, but it safely touched down around three hours later. None of the 174 passengers or seven crew members on board were injured. <div class="embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border: 0px; font-size: 16px; vertical-align: baseline; outline: none !important;"><iframe class="embedly-embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border-width: 0px; border-style: initial; vertical-align: baseline; width: 573px; max-width: 100%; outline: none !important;" title="tiktok embed" src="https://cdn.embedly.com/widgets/media.html?src=https%3A%2F%2Fwww.tiktok.com%2Fembed%2Fv2%2F7389507936625691920&display_name=tiktok&url=https%3A%2F%2Fwww.tiktok.com%2F%40theprojecttv%2Fvideo%2F7389507936625691920%3Fq%3Dboeing%2520wheel%26t%3D1720568253683&image=https%3A%2F%2Fp16-sign-sg.tiktokcdn.com%2Fobj%2Ftos-alisg-p-0037%2FoEEROKIMm2EpV6DrBgf3FeAUB4EjlBg0BMjmzE%3Flk3s%3Db59d6b55%26nonce%3D85756%26refresh_token%3D9848a1a77a4d011f7ceeb76a41229609%26x-expires%3D1720738800%26x-signature%3DKRkuV5%252BXkjrhdVj9cxtL5oLH5ow%253D%26shp%3Db59d6b55%26shcp%3D-&key=5b465a7e134d4f09b4e6901220de11f0&type=text%2Fhtml&schema=tiktok" width="340" height="700" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe></div> A United spokesperson said that the wheel has been found in Los Angeles and they are investigating the cause. “The wheel has been recovered in Los Angeles, and we are investigating what caused this event,” the statement read.

Flight attendant reveals the unexpected reason why it's so cold on planes

When it comes to packing essentials in your carry-on for your next flight, many people add a jumper, extra socks, or even their own blanket to their bags. Because one thing’s for sure: you’ll probably be cold on your flight. But have you ever stopped to think of the reason why the cabin of a plane is so cold? According to a Canadian flight attendant, it's to do with keeping you feeling good. Vanessa Settimi told Reader's Digest that a cooler cabin helps passengers who are prone to fainting or have motion sickness during turbulence. She also clarified that despite what travellers may think, cabin crew don’t have control over the cabin temperature. "Temperature in the cabin is controlled by the pilots. Even though travellers often ask to get the temperature turned up during flights, it is kept on the cooler side." She went on to say that the key to staying warm on your next flight is bringing extra layers. "Now this might just be the flight attendant in me," says Settimi, "but you will never catch me flying as a traveller in sandals and a tank top!" Image credits: Shutterstock

The surprising reason commercial planes are painted white

Up until the middle of the last century, airplanes would fly through the sky unpainted as shiny silver tubes. But now, we are so used to seeing plane bodies being painted white, with the exception of the airline’s logo and a splash of colour on the plane’s tail. But this drastic look isn’t just about style and uniformity, as there is a simple reason why plane bodies are left plain. First of all, white paint jobs will show wear and tear a lot quicker on huge commercial planes and while this might not be ideal for a car or house, it's perfect for planes. From takeoff to landing, a plane goes through a lot. While the aircrafts are always deemed safe for flying, it'll likely suffer minor cosmetic damages as it hurtles through the sky at 900 kilometres per hour. Due to the frequent minor chips and scratches a plane has inflicted, using the white paint helps engineers and maintenance teams to spot any of these issues with ease. Another reason that white is uniform in the skies is because white paint is going to fade at a much slower rate than a darker shade. As planes fly above the clouds, they're exposed to a lot of UV rays which speeds up the process of the paint fading. Lastly, it's been found that birds can spot planes against the sky easier when they're painted all-white, as sometimes in rare occasions, birds can pose a safety risk. It wasn’t until 50 years ago that airlines started painting their planes, with Air France being credited for starting the movement in the 1970s. "Since Air France introduced the first 'Euro-white' livery in 1976, the all-white fuselage look has become increasingly standard for the world's airlines," aviation historian Shea Oakley told Travel + Leisure.

Pioneering TV presenter reveals terminal diagnosis live on air

Popular New Zealand TV presenter Joanna Paul-Robie has revealed she is dying of cancer. The pioneering presenter, known for her work on TV3, shared the heartbreaking news during an interview with Radio New Zealand on Friday morning. Paul-Robie, who has been a beloved figure in the broadcasting world, made the announcement while accepting the Icon Award for her contributions to the creative industries. “I was so touched because this award means so much to me, coming from Tauranga Moana,” she said. “But more importantly, because I am, unfortunately, dying – I have terminal cancer – and really to have this award before one posthumously gets it is an even better break. I can’t tell you the lightness, the brightness, the feeling of aroha inside me last night.” Reflecting on her career, Paul-Robie recounted her experiences as one of the few Māori individuals on New Zealand's television screens. “The newsroom was really … it was being run by mostly a pair of middle-class, middle-aged white men who had the audacity and the balls to say ‘If it bleeds, it leads’ but these guys you know they had never been in a Māori world,” she remarked. Starting her career at Radio New Zealand, Paul-Robie later became a newsreader for TV3 and played a significant role in establishing Māori Television in 2004, serving as a program and production manager. During a 2011 interview with NZOnScreen, she spoke about the challenges and triumphs of setting up the network. “There’s been a handful of people in the world who have built a television station and taken it to air,” she said. “There are only a handful of people in the world who can do that and even though it nearly broke me in half on the day that we launched, I thought ‘hell we did that’. I think it is difficult for someone like me with an A-type personality to think now you have done your big thing maybe you should take it easy now.” Paul-Robie's courage and dedication have left an indelible mark on New Zealand's broadcasting landscape. Her announcement has been met with an outpouring of support and love from colleagues, fans and the wider community, who admire her strength and resilience in the face of such a personal battle.

Almost half the men surveyed think they could land a passenger plane. Experts disagree

Are there any passengers who could land this plane with assistance from air traffic control? </blockquote> If you think you could manage it, you’re not alone. <a href="https://today.yougov.com/topics/politics/survey-results/daily/2023/01/02/fd798/3">Survey results</a> published in January indicate about one-third of adult Americans think they could safely land a passenger aircraft with air traffic control’s guidance. Among male respondents, the confidence level rose to nearly 50%. Can a person with no prior training simply guide everyone to a smooth touchdown? We’ve all heard stories of passengers who saved the day when the pilot became unresponsive. For instance, last year <a href="https://www.youtube.com/watch?v=qbMoyWukjbs">Darren Harrison</a> managed to land a twin-engine aircraft in Florida – after the pilot passed out – with the guidance of an air traffic controller who also happened to be a flight instructor. However, such incidents tend to take place in small, simple aircraft. Flying a much bigger and heavier commercial jet is a completely different game. <h2>You can’t always rely on autopilot</h2> A pilot spends about 90% of their time monitoring autopilot systems and making sure everything is working as intended. The other 10% is spent managing problems, taxiing, taking off and landing. Takeoffs and landings are arguably the most difficult tasks pilots perform, and are always performed manually. Only on very few occasions, and in a handful of aircraft models, can a pilot use autopilot to land the aircraft for them. This is the exception, and not the rule. For takeoff, the aircraft must build up speed until the wings can generate enough lift to pull it into the air. The pilot must <a href="https://youtu.be/16XTAK-4Xbk?si=66yDo5g5I086Q2y2&t=65">pay close attention</a> to multiple instruments and external cues, while keeping the aircraft centred on the runway until it reaches lift-off speed. Once airborne, they must coordinate with air traffic control, follow a particular path, retract the landing gear and maintain a precise speed and direction while trying to climb. Landing is even more complicated, and requires having precise control of the aircraft’s direction and descent rate. <a href="https://youtu.be/u_it9OiTnSM?si=xNZrLB9ZH870LEa3&t=360">To land successfully</a>, a pilot must keep an appropriate speed while simultaneously managing gear and flap configuration, adhering to air traffic regulations, communicating with air traffic control and completing a number of paper and digital checklists. Once the aircraft comes close to the runway, they must accurately judge its height, reduce power and adjust the rate of descent – ensuring they land on the correct area of the runway. On the ground, they will use the brakes and reverse thrust to bring the aircraft to a complete stop before the runway ends. This all happens within just a few minutes. <figure><iframe src="https://www.youtube.com/embed/Nyx4NyMrvOs?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> Both takeoff and landing are far too quick, technical and concentration-intensive for an untrained person to pull off. They also require a range of skills that are only gained through extensive training, such as understanding the information presented on different gauges, and being able to coordinate one’s hands and feet in a certain way. <h2>Training a pilot</h2> The journey from student to commercial pilot is a long one. It normally starts with a recreational licence, followed by a private licence, and then a commercial licence (which allows them to fly professionally). Even before stepping into a cockpit, the student must study aerodynamics, air law and flight rules, meteorology, human factors, navigation, aircraft systems, and performance and flight planning. They also need to spend time learning about the specific aircraft they will be flying. Once the fundamentals are grasped, an instructor takes them for training. Most of this training is conducted in small, lightweight aircraft – with a simulator introduced briefly towards the end. During a lesson, each manoeuvre or action is demonstrated by the instructor before the student attempts it. Their attempt may be adjusted, corrected or even terminated early in critical situations. The first ten to fifteen lessons focus on takeoff, landing, basic in-flight control and emergency management. When the students are ready, they’re allowed to “go solo” – wherein they conduct a complete flight on their own. This is a great milestone. After years of experience, they are ready to transition to a commercial aircraft. At this point they might be able to take off and land reasonably well, but they will still undergo extensive training specific to the aircraft they are flying, including hours of advanced theory, dozens of simulator sessions and hundreds of hours of real aircraft training (most of which is done with passengers onboard). So, if you’ve never even learned the basics of flying, your chances of successfully landing a passenger aircraft with air traffic control’s help are close to zero. <h2>Yet, flying is a skill like any other</h2> Aviation training has been democratised by the advent of high-end computers, virtual reality and flight simulation games such as Microsoft’s <a href="https://www.flightsimulator.com/">Flight Simulator</a> and <a href="https://www.x-plane.com/">X-Plane</a>. Anyone can now rig up a desktop flight simulator for a few thousand dollars. Ideally, such a setup should also include the basic physical controls found in a cockpit, such as a control yoke, throttle quadrant and pedals. Flight simulators provide an immersive environment in which professional pilots, students and aviation enthusiasts can develop their skills. So if you really think you could match-up against a professional, consider trying your hand at one. You almost certainly won’t be able to land an actual passenger plane by the end of it – but at least you’ll gain an appreciation for the immense skill pilots possess.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/218037/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/guido-carim-junior-1379129">Guido Carim Junior</a>, Senior Lecturer in Aviation, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a>; <a href="https://theconversation.com/profiles/chris-campbell-1414564">Chris Campbell</a>, Adjunct Associate Professor, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a>; <a href="https://theconversation.com/profiles/elvira-marques-1362476">Elvira Marques</a>, Aviation PhD candidate, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a>; <a href="https://theconversation.com/profiles/nnenna-ike-1490692">Nnenna Ike</a>, Research Assistant, Griffith Aviation, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a>, and <a href="https://theconversation.com/profiles/tim-ryley-1253269">Tim Ryley</a>, Professor and Head of Griffith Aviation, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why you shouldn’t worry if the plane cabin fills with fog

A savvy traveller has shared why plane cabins can fill with fog, and why you need not to worry about it. Passenger Savannah Gowarty posted a video of the suspiciously looking inflight mist and condensation on a domestic US flight, with the video garnered over 13.1 million views, and amazing and confusing commentators questioning what was going on. In response to the viral video, a Federal Aviation Administration (FAA) spokesperson told <a href="https://cnn.com/travel">CNN Travel</a> what it means. The short answer: it's a natural occurrence that usually only lasts a short while, and it's nothing to worry about. "On hot and relatively humid days, cold air from the aircraft's air conditioning system mixes with the warmer, humid cabin air and lowers it to the dew point, creating fog," the spokesperson said. "The fog is generally short-lived as the cooled air quickly warms above the dew point." When an airplane is waiting on the ground pre-departure, the aircraft cabin air is kept cool "either from an external ground air conditioning unit or the aircraft's own Auxiliary Power Unit (APU)," as the FAA spokesperson explains. "Both provide cold air (usually much cooler than the ambient temperature) which can temporarily lower the dew point of the aircraft cabin air enough to create fog." Climate scientist Indrani Roy emphasised that neither mist nor any resulting condensation is "cause for alarm." The FAA spokesperson went on to explain that "aircraft cabin fog usually dissipates very quickly." "This is due to the colder air (which lowered the cabin air temperature to its dew point) quickly warms back above the dew point. Once that happens, the fog will disappear.” “Many times, the fog only appears as it comes out of the vent, exists for 1-2 seconds and then is gone." Image credits: Shutterstock

<a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> This week has seen another barrage of <a href="https://www.theguardian.com/uk-news/2024/jan/22/uk-weather-storm-jocelyn-to-follow-isha-with-more-strong-winds-and-heavy-rain">unsettled weather</a> sweep across the UK, with many flights delayed or cancelled. Some of those who were fortunate enough to take off found themselves arriving at destinations that weren’t on their boarding passes – such as passengers travelling from Stansted to Newquay who eventually diverted to <a href="https://uk.news.yahoo.com/storm-isha-creates-flight-diversion-142821278.html">Malaga</a>. One thing that was consistently described by passengers was that parts of the flights and the attempted landings were some of the most unnerving they’d ever experienced, due to turbulence. Turbulence results from uneven air movement, which is <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023GL103814">increasing</a> in frequency. If you turn your hair dryer on at home and hold it still, the air moves at a constant rate, but once you begin drying your hair and moving the hairdryer around, the air movement becomes uneven, that is to say, turbulent. Although turbulence may be unnerving and make you feel unwell, it is important to recognise that it is very common and typically <a href="https://pubmed.ncbi.nlm.nih.gov/18018437/">nothing to worry about</a> if you’re in your seat with your seatbelt fastened. <h2>How the body detects and responds to turbulence</h2> The body recognises itself within any environment. Its relationship with objects in terms of distance and direction is called <a href="https://www.sciencedirect.com/science/article/abs/pii/B9780123750006003414">spatial orientation</a>. When flying, this is typically moving forwards, ascending, some turns and a descent. However, turbulence disrupts this relationship and confuses the sensory information being received by the brain – it makes the body want to respond or recalibrate. Our inner ears play a pivotal role in all this. It consists of complex apparatuses that undertake more than hearing. These include the cochlea, <a href="https://www.ncbi.nlm.nih.gov/books/NBK279394/">three semi-circular canals</a>, <a href="https://radiopaedia.org/articles/utricle-ear?lang=gb">the utricle</a> and <a href="https://radiopaedia.org/articles/saccule-ear-1?lang=gb">the saccule</a>. The cochlea is responsible for hearing. It converts <a href="https://www.ncbi.nlm.nih.gov/books/NBK531483/">sound energy into electrical energy</a> that is then “heard” by the brain. The remaining structures are responsible for the balance and position of the head and body. The semi-circular canals are positioned in a vertical (side to side), horizontal and front-to-back plane, detecting movement in a nodding, shaking and touching ear-to-shoulder direction. Attached to these canals are <a href="https://www.ncbi.nlm.nih.gov/books/NBK532978/">the utricle and saccule</a>, which can detect <a href="https://www.ncbi.nlm.nih.gov/books/NBK10792/">movement</a> and <a href="https://www.cell.com/current-biology/pdf/S0960-9822(05)00837-7.pdf">acceleration</a>. All of these apparatuses use microscopic hair cells in a specialised fluid called <a href="https://www.ncbi.nlm.nih.gov/books/NBK531505/">endolymph</a> that flows with the head to create a sense of movement. When the plane encounters turbulence, this fluid moves around, but unpredictably. It takes <a href="https://www.ncbi.nlm.nih.gov/books/NBK518976/">about ten to 20 seconds</a> for the fluid to recalibrate its position, while the brain struggles to understand what is going on. When the aircraft hits turbulence, the balance apparatus <a href="https://www.frontiersin.org/articles/10.3389/fneur.2023.949227/full">cannot distinguish</a> the movement of the plane from that of the head, so the brain interprets the aircraft movement as that of the head or body. But this doesn’t match the visual information being received, which causes sensory confusion. The reason the inner ear causes so much confusion is because during flights you are devoid of your primary sensory tool relative to the external environment – your sight and the horizon. Eighty per cent of <a href="https://www.ncbi.nlm.nih.gov/books/NBK518976/">spatial information</a> comes from your eyes during flight. However, you only have the seat in front of you or the cabin as a reference point, which means your inner ear becomes the dominant sensory message to the brain during turbulence and disrupts the <a href="https://www.ncbi.nlm.nih.gov/books/NBK545297/">“vestibulo-ocular reflex”</a>. This reflex keeps your vision <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4130651/">aligned</a> with your balance or expected position. Vision is the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6777262/">most valued</a> of the senses and one-third of the brain is attributed to its function, reinforcing its importance in spatial orientation. This sensory mixed messaging often results in things like dizziness and sweating as well as gastrointestinal symptoms, such as <a href="https://www.airmedicaljournal.com/article/S1067-991X(02)70038-2/fulltext">nausea and vomiting</a>. Motion sickness can be triggered by turbulence and although research into specific airsickness is limited, other modes that induce motion sickness suggest that <a href="https://pubmed.ncbi.nlm.nih.gov/16018346/">women</a> are <a href="https://pubmed.ncbi.nlm.nih.gov/26466829/">more susceptible</a> than men, particularly in the <a href="https://pubmed.ncbi.nlm.nih.gov/16235881/">early stages</a> of the menstrual cycle. The turbulence also causes an increase in your heart rate, which is already higher than normal when flying because of a <a href="https://pubmed.ncbi.nlm.nih.gov/15819766/">decrease in oxygen saturation</a>. <h2>What about the pilots?</h2> Commercial pilots accrue thousands of hours at the controls, they are subject to the same forces as the passengers. Over time, they can <a href="https://academic.oup.com/milmed/article/180/11/1135/4160573">adapt to these forces</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/15828634/">experiences</a>, but they also have a couple of additional resources that most passengers don’t. They have the view out of the cockpit windows, so have a horizon to use as a reference point and can see what lies immediately ahead. If it is cloudy or visibility is low, their instruments provide additional visual <a href="https://www.faa.gov/sites/faa.gov/files/regulations_policies/handbooks_manuals/aviation/phak/19_phak_ch17.pdf">reference</a> to the position of the aircraft. This doesn’t mean they are immune to the effects of turbulence, with some studies reporting up to <a href="https://pubmed.ncbi.nlm.nih.gov/26540704/">71% of trainee pilots</a> reporting episodes of airsickness. <h2>How to reduce the discomfort</h2> A window seat can help, or even looking out the window. This gives the brain some sensory information through visual pathways, helping calm the brain in response to the vestibular information it is receiving. If you can get one, a seat towards the front or over the wing reduces the effects of turbulence. Deep or rhythmical breathing can help reduce motion sickness induced by turbulence. Focusing on your breathing <a href="https://pubmed.ncbi.nlm.nih.gov/25945662/">calms the nervous system</a>. Don’t reach for the alcohol. While you may feel it calms your nerves, if you hit turbulence it’s going to interfere with your <a href="https://pubmed.ncbi.nlm.nih.gov/7610847/">visual and auditory processing</a> and increase the likelihood of vomiting. If you suffer from motion sickness and are worried about turbulence while flying, then there are also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6241144/">drugs that can help</a>, including certain <a href="https://www.nhs.uk/medicines/cinnarizine/about-cinnarizine/">antihistamines</a>. Finally, it’s important to remember that although turbulence can be unpleasant, aircraft are designed to withstand the forces it generates and many passengers, even frequent fliers, will rarely encounter the most severe categories of turbulence because pilots actively plan routes to avoid it.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/221780/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, Professor and Director of the Clinical Anatomy Learning Centre, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"Not one ounce of compassion”: BBC star kicked off plane over daughter's allergy

A BBC weather presenter and her family have been kicked off a plane after asking passengers to be wary of her daughter's peanut allergy. British weather presenter Georgie Palmer was flying from London to Turkey with her husband Matt and their daughters Annie and Rosie, as the family boarded their flight at Gatwick Airport with SunExpress airlines. Georgie and her family were kicked off the plane shortly after boarding, after the 49-year-old mother ran into issues around her daughter's severe allergy to peanuts. According to Palmer, she has requested that the captain make an announcement to all passengers asking them not to eat any peanut products on the flight, but the pilot refused. Palmer then took matters into her own hands and one by one asked passengers not to consume peanuts on the four-hour flight, before being asked to disembark the aircraft. The weather presenter took to Instagram to share her side of the story with a lengthy post. She began, “I thanked the beautiful souls on our plane for helping us. Many of them hugged, cheered and held our hands as we were forced to disembark." “The SunExpress captain and cabin crew refused to make the standard announcement on behalf of our daughter. We gently asked the passengers at the front of the plane to share our request." “Row by row, all the passengers turned back to kindly ask the row behind to please not eat nuts on the flight. It was calm, earnest and with an overwhelming sense of solidarity and empathy.” Georgie added: “There’s no beef with simple asks like these. People get it!" “We were hoofed off the plane after the angry little captain shouted at us from the cockpit.” She concluded by saying they were discriminated against for “simply having an allergy”. Georgie told the <a title="www.dailymail.co.uk" href="https://www.dailymail.co.uk/news/article-13457399/bbc-weather-presenter-Georgie-Palmer-flight-nuts.html" target="_blank" rel="noopener">Daily Mail,</a> “The captain decided because of my daughter’s allergy he didn’t want to fly with her on board." “When he found out I had spoken to the other passengers he was screaming at me from the cockpit. He was so angry, the next thing I knew we were told to get off the plane." “How we were treated was disgusting – nobody working on that plane showed one ounce of compassion.” A SunExpress spokesman then shared the airline's version of events, claiming that Georgie's husband had become aggressive, and kicked the family off the plane with their best interests at heart. The statement said, “We take the safety of our passengers very seriously. Shortly after boarding our flight, the passenger raised a concern about one of his family group having a serious peanut allergy." “They requested an announcement to other passengers. We refrain from making these kinds of announcements. Like many other airlines, we cannot guarantee an allergen-free environment on our flights, nor can we prevent other passengers from bringing food items containing allergens on board." “Due to the insistent behaviour of the passenger to others on board, the captain decided it would be safest if the family did not travel." “When this was explained to the passenger, he behaved aggressively towards our crew members and tried to gain access to the cockpit. To ensure the safety of our crew and our passengers on board, we cannot tolerate aggressive and unruly behaviour on our flights." “Our website states that passengers must notify us 48 hours in advance of any special care required due to a medical condition. No such notification was received from the passengers in this instance.” According to <a href="https://www.thesun.co.uk/tv/28140666/bbc-family-flight-passengers-peanuts-allergy/" target="_blank" rel="noopener">The Sun</a>, Mr Sollom denies acting aggressively. The differing versions of events have divided many on social media as thousands weighed in on the debacle, with plenty of users siding with the pilot. “The pilot is a national treasure,” one person wrote. “As they should have been,” a second wrote, referring to the family getting kicked off. “Would have booted them off as well,” another agreed. A fourth wrote: “I think this story would be found under Self Entitlement in the dictionary.” Image credits: Instagram

How risky is turbulence on a plane? How worried should I be?

<a href="https://theconversation.com/profiles/hassan-vally-202904">Hassan Vally</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> The Singapore Airlines <a href="https://www.abc.net.au/news/2024-05-21/singapore-london-flight-makes-emergency-landing/103876370">turbulence incident</a> that has sadly left one person dead and others hospitalised has made many of us think about the risks of air travel. We’ll hear more in coming days about how the aircraft came to drop so suddenly on its route from London to Singapore earlier this week, injuring passengers and crew, before making an emergency landing in Thailand. But thankfully, these types of incidents <a href="https://www.atsb.gov.au/publications/2014/in-flight-turbulence">are rare</a>, and much <a href="https://www.aihw.gov.au/reports/injury/transport-accidents">less-common</a> than injuries from other types of transport. So why do we sometimes think the risk of getting injured while travelling by plane is higher than it really is? <h2>How common are turbulence injuries?</h2> <a href="https://theconversation.com/what-is-air-turbulence-196872">Turbulence</a> <a href="https://www.atsb.gov.au/publications/2014/in-flight-turbulence">is caused by</a> the irregular movement of air, leading to passengers and crew experiencing abrupt sideways and vertical jolts. In the case of the Singapore Airlines flight, this type of turbulence is thought to be a severe example of “<a href="https://www.theguardian.com/business/article/2024/may/21/what-causes-air-turbulence-and-how-worried-should-passengers-be">clear-air turbulence</a>”, which can occur without warning. There are several other types. About 25 in-flight turbulence injuries <a href="https://www.atsb.gov.au/publications/2014/in-flight-turbulence">are reported</a> to the Australian Transport Safety Bureau each year, although it is thought many more are un-reported. Some of these reported injuries are serious, including broken bones and head injuries. Passengers being thrown up and out of their seat during turbulence is one of the most common type of head injury on a plane. Other injuries from turbulence are caused by contact with flying laptops, or other unsecured items. In <a href="https://www.atsb.gov.au/sites/default/files/2023-04/AR-2008-034%20Turbulence%20FactSheet_v2.pdf">one example</a> of clear-air turbulence that came without warning, cabin crew, passengers and meal trolleys hit the ceiling, and landed heavily back on the floor. Serious injuries included bone fractures, lacerations, neck and back strains, a dislocated shoulder and shattered teeth. Almost all of those seriously injured did not have their seat belts fastened. But we need to put this into perspective. In the year to January 2024, there were <a href="https://www.bitre.gov.au/statistics/aviation/international">more than 36 million</a> passengers on international flights to Australia. In the year to February 2024, there were <a href="https://www.bitre.gov.au/statistics/aviation/domestic">more than 58 million</a> passengers on domestic flights. So while such incidents grab the headlines, they are exceedingly rare. <h2>Why do we think flying is riskier than it is?</h2> When we hear about this recent Singapore Airlines incident, it’s entirely natural to have a strong emotional reaction. We might have imagined the terror we might feel if we were on the aircraft at the time. But our emotional response <a href="https://psycnet.apa.org/record/2001-16969-005">alters our perception</a> of the risk and leads us to think these rare incidents are more common than they really are. There is a vast body of literature addressing the <a href="https://theconversation.com/explainer-how-our-understanding-of-risk-is-changing-79501">numerous factors</a> that influence how individuals perceive risk and the cognitive biases we are all subject to that mislead us. Nobel Prize-winning economist <a href="https://www.nobelprize.org/prizes/economic-sciences/2002/kahneman/facts/">Daniel Kahneman</a> covers them in his bestselling book <a href="https://www.penguin.com.au/books/thinking-fast-and-slow-9780141033570">Thinking, Fast and Slow</a>. He describes the way we respond to risks is not rational, but driven by emotion. Kahneman also highlights the fact that our brains are not wired to make sense of extremely small risks. So these types of risks – such as the chance of serious injury or death from in-flight turbulence – are hard for us to make sense of. The more unusual an event is, and this was a very unusual event, Kahneman says the more impact it makes on our psyche and the more likely we are to overestimate the risk. Of course, the more unusual the event, the <a href="https://psycnet.apa.org/record/1999-02435-000">more likely</a> it is for it to be in the media, amplifying this effect. Similarly, the easier it is to <a href="https://www.sciencedirect.com/science/article/abs/pii/0010028573900339">imagine an event</a>, the more it affects our perception and the more likely we are to respond to an event as if it were much more likely to occur. <h2>How can we make sense of the risk?</h2> One way to make sense of activities with small, hard-to-understand risks is by comparing their risks to the risks of more familiar activities. If we do this, the data shows very clearly that it is much <a href="https://www.aihw.gov.au/reports/injury/transport-accidents">more risky</a> to drive a car or ride a motorbike than to travel by plane. While events such as the Singapore Airlines incident are devastating and stir up lots of emotions, it’s important to recognise how our emotions can mislead us to over-estimate the risk of this happening again, or to us. Apart from the stress and anxiety this provokes, overestimating the risks of particular activities may lead us to make bad decisions that actually put us at greater risk of harm.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/230665/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/hassan-vally-202904">Hassan Vally</a>, Associate Professor, Epidemiology, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Are some routes more prone to air turbulence? Will climate change make it worse? Your questions answered

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/doug-drury-1277871">Doug Drury</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a> A little bit of turbulence is a common experience for air travellers. Severe incidents are rare – but when they occur they can be deadly. The recent Singapore Airlines flight SQ321 from London to Singapore shows the danger. An <a href="https://apnews.com/article/singapore-airlines-flight-turbulence-5a9a268e1a6a6fb9ece7e58b5ea9231b">encounter with extreme turbulence</a> during normal flight left one person dead from a presumed heart attack and several others badly injured. The flight diverted to land in Bangkok so the severely injured passengers could receive hospital treatment. Air turbulence can happen anywhere, but is far more common on some routes than on others. Climate change is expected to boost the chances of air turbulence, and make it more intense. In fact, <a href="https://www.nature.com/articles/s41586-019-1465-z">some research</a> indicates turbulence <a href="https://theconversation.com/aviation-turbulence-soared-by-up-to-55-as-the-world-warmed-new-research-207574">has already worsened</a> over the past few decades. <h2>Where does turbulence happen?</h2> Nearly every flight experiences turbulence in one form or another. If an aircraft is taking off or landing behind another aircraft, the wind generated by the engine and <a href="https://www.faa.gov/air_traffic/publications/atpubs/aim_html/chap7_section_4.html">wingtips</a> of the lead aircraft can cause “wake turbulence” for the one behind. Close to ground level, there may be turbulence due to strong winds associated with weather patterns moving through the area near an airport. At higher altitudes, there may be wake turbulence again (if flying close to another aircraft), or turbulence due to updraughts or downdraughts from a thunderstorm. Another kind of turbulence that occurs at higher altitudes is harder to predict or avoid. So-called “<a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023gl103814">clear-air turbulence</a>” is invisible, as the name suggests. It is often caused by warmer air rising into cooler air, and is generally expected to get worse due to climate change. At the most basic level turbulence is the result of two or more wind events colliding and creating eddies, or swirls of <a href="https://www.nationalgeographic.com/travel/article/what-is-turbulence-explained">disrupted airflow</a>. It often occurs near mountain ranges, as wind flowing over the terrain accelerates upward. Turbulence also often occurs at the edges of the <a href="https://www.nationalgeographic.com/travel/article/what-is-turbulence-explained">jet streams</a>. These are narrow bands of strong, high-altitude winds circling the globe. Aircraft often travel in the jet streams to get a speed boost – but when entering or leaving the jet stream, there may be some turbulence as it crosses the boundary with the slower winds outside. <h2>What are the most turbulent routes?</h2> It is possible to <a href="https://turbli.com/maps/world-turbulence-map/">map turbulence patterns</a> over the whole world. Airlines use these maps to plan in advance for alternate airports or other essential contingencies. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=430&fit=crop&dpr=1 600w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=430&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=430&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=541&fit=crop&dpr=1 754w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=541&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=541&fit=crop&dpr=3 2262w" alt="Map showing air turbulence." /></a><figcaption>A map of estimated clear-air turbulence around the world, current as of 3:00PM AEST (0500 UTC) on May 22 2024. <a class="source" href="https://turbli.com/maps/world-turbulence-map/">Turbli</a></figcaption></figure> While turbulence changes with weather conditions, some regions and routes are more prone to it than others.

Weather radar imagery shows the pilots where the most intense turbulence can be expected, and they work with air traffic control to avoid those areas. When turbulence is encountered unexpectedly, the pilots immediately turn on the “fasten seatbelt” sign and reduce engine thrust to slow down the plane. They will also be in touch with air traffic control to find better conditions either by climbing or descending to smoother air. Ground-based meteorological centres can see weather patterns developing with the assistance of satellites. They provide this information to flight crews in real time, so the crew knows the weather to expect throughout their flight. This can also include areas of expected turbulence if storms develop along the intended flight route. It seems we are heading into more turbulent times. Airlines will do all they can to reduce the impact on planes and passengers. But for the average traveller, the message is simple: when they tell you to fasten your seatbelt, you should listen.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/230666/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/doug-drury-1277871">Doug Drury</a>, Professor/Head of Aviation, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"Not going to save anybody": Exit row passenger prompts plane evacuation

A whole plane has been forced to disembark after a woman seated in the exit row refused to comply with safety instructions. Passengers were up in arms when they had to leave the plane, after the woman was overheard telling cabin crew that she would only save herself in the event of an emergency, before yelling at flight attendants. The interaction, which was captured by another passenger on video and posted to TikTok, shows the woman becoming heated while talking to cabin crew on the Frontier flight. The passenger can then be seen and heard progressively raising her voice to cabin crew, with fellow flyers pleading with the woman to disembark the plane. The traveller who filmed the altercation claims the woman said she was “not going to save anybody” when seated in the exit row, saying the disgruntled passenger had “attitude” and went on to say that if something were to happen, she would “only save” herself. “That was her attitude throughout the seating process. And I already knew something was about to pop off when she had that attitude,” the TikTok user said. The altercation only became more heated as the yelling progressed, before police eventually arrived on the plane to escort the woman off. The video then shows another Frontier employee approach the passenger and say, “I’m gonna ask you one more time, nicely, to get off, if not, we’re going to deboard the plane and police will come and escort you off.” When the cabin crew make repeated futile attempts to get through the woman, the pilot came down from the cockpit to try and call for calm. “You’re inconveniencing everybody else,” the pilot can be heard saying to the woman. as the pair continue to exchange words while he repeatedly points toward the front of the plane. Following the failed attempts, two police officers then make their way down the aisle and towards the passenger. Towards the end of the five-minute video, which has been viewed more than 80,000 times, all the passengers on board the flight were filmed disembarking the aircraft while the passenger at the centre of the ordeal exits with police from a separate door onto the tarmac. It is unclear if charges were laid. Image credits: TikTok

Air travel exposes you to radiation – how much health risk comes with it?

<a href="https://theconversation.com/profiles/timothy-j-jorgensen-239253">Timothy J. Jorgensen</a>, <a href="https://theconversation.com/institutions/georgetown-university-1239">Georgetown University</a> In 2017, <a href="http://www.independent.ie/business/world/18-million-miles-and-counting-the-globes-top-business-traveller-35666790.html">business traveler Tom Stuker</a> was hailed as the world’s most frequent flyer, logging 18,000,000 miles of air travel on United Airlines over 14 years. That’s a lot of time up in the air. If Stuker’s traveling behaviors are typical of other business flyers, he may have eaten 6,500 <a href="http://www.airliners.net/forum/viewtopic.php?t=689041">inflight meals</a>, drunk 5,250 <a href="https://doi.org/10.1111/j.1708-8305.2009.00339.x">alcoholic beverages</a>, watched thousands of <a href="http://www.iata.org/publications/store/Pages/global-passenger-survey.aspx">inflight movies</a> and made around 10,000 visits to <a href="http://blog.thetravelinsider.info/2012/11/how-many-restrooms-are-enough-on-a-plane.html">airplane toilets</a>. He would also have accumulated a radiation dose equivalent to about 1,000 <a href="https://www.radiologyinfo.org/en/info.cfm?pg=safety-xray">chest x-rays</a>. But what kind of health risk does all that radiation actually pose? <h2>Cosmic rays coming at you</h2> You might guess that a frequent flyer’s radiation dose is coming from the airport security checkpoints, with their whole-body scanners and baggage x-ray machines, but you’d be wrong. The <a href="http://www.aapm.org/publicgeneral/AirportScannersPressRelease.asp">radiation doses to passengers from these security procedures</a> are trivial. The major source of radiation exposure from air travel comes from the flight itself. This is because at high altitude the <a href="http://www.altitude.org/why_less_oxygen.php">air gets thinner</a>. The farther you go from the Earth’s surface, the fewer molecules of gas there are per volume of space. Thinner air thus means fewer molecules to deflect incoming <a href="http://www.space.com/32644-cosmic-rays.html">cosmic rays</a> – radiation from outer space. With less <a href="http://www.bbc.co.uk/science/earth/atmosphere_and_climate/atmosphere">atmospheric shielding</a>, there is more exposure to radiation. The most extreme situation is for astronauts who travel entirely outside of the Earth’s atmosphere and enjoy none of its protective shielding. Consequently, they receive high radiation doses. In fact, it is the accumulation of radiation dose that is the limiting factor for the maximum length of manned space flights. Too long in space and <a href="https://www.nasa.gov/hrp/bodyinspace">astronauts risk cataracts, cancer and potential heart ailments</a> when they get back home. Indeed, it’s the radiation dose problem that is a major spoiler for <a href="http://www.space.com/34210-elon-musk-unveils-spacex-mars-colony-ship.html">Elon Musk’s goal of inhabiting Mars</a>. An extended stay on Mars, with its <a href="http://www.space.com/16903-mars-atmosphere-climate-weather.html">extremely thin atmosphere</a>, would be lethal due to the high radiation doses, notwithstanding Matt Damon’s successful Mars colonization in the movie <a href="https://www.youtube.com/watch?v=ej3ioOneTy8">“The Martian</a>.” <h2>Radiation risks of ultra frequent flying</h2> What would be Stuker’s cumulative radiation dose and what are his health risks? It depends entirely on how much time he has spent in the air. Assuming an <a href="http://hypertextbook.com/facts/2002/JobyJosekutty.shtml">average flight speed</a> (550 mph), Stuker’s 18,000,000 miles would translate into 32,727 hours (3.7 years) of flight time. The radiation dose rate at typical <a href="http://www.telegraph.co.uk/travel/travel-truths/why-do-planes-fly-so-high-feet/">commercial airline flight altitude</a> (35,000 feet) is about <a href="https://hps.org/publicinformation/ate/faqs/commercialflights.html">0.003 millisieverts per hour</a>. (As I explain in my book <a href="http://press.princeton.edu/titles/10691.html">“Strange Glow: The Story of Radiation</a>,” a millisievert or mSv is a unit of radiation dose that can be used to estimate cancer risk.) By multiplying the dose rate by the hours of flight time, we can see that Stuker has earned himself about 100 mSv of radiation dose, in addition to a lot of free airline tickets. But what does that mean for his health? The primary health threat at this dose level is an increased risk of some type of cancer later in life. Studies of atomic bomb victims, nuclear workers and medical radiation patients have <a href="https://doi.org/10.17226/11340">allowed scientists to estimate the cancer risk</a> for any particular radiation dose. All else being equal and assuming that low doses have risk levels proportionate to high doses, then an overall cancer risk rate of <a href="http://www.imagewisely.org/imaging-modalities/computed-tomography/medical-physicists/articles/how-to-understand-and-communicate-radiation-risk">0.005 percent per mSv</a> is a reasonable and commonly used estimate. Thus, Stuker’s 100-mSv dose would increase his lifetime risk of contracting a potentially fatal cancer by about 0.5 percent. <h2>Contextualizing the risk</h2> The question then becomes whether that’s a high level of risk. Your own feeling might depend on how you see your background cancer risk. Most people <a href="http://www.who.int/whr/2002/chapter3/en/index4.html">underestimate their personal risk of dying from cancer</a>. Although the exact number is debatable, it’s fair to say that <a href="https://www.cancer.org/cancer/cancer-basics/lifetime-probability-of-developing-or-dying-from-cancer.html">about 25 percent of men ultimately contract a potentially fatal cancer</a>. Stuker’s 0.5 percent cancer risk from radiation should be added to his baseline risk – so it would go from 25 percent to 25.5 percent. A cancer risk increase of that size is too small to actually measure in any scientific way, so it must remain a theoretical increase in risk. A 0.5 percent increase in risk is the same as one chance in 200 of getting cancer. In other words, if 200 male travelers logged 18,000,000 miles of air travel, like Stuker did, we might expect just one of them to contract a cancer thanks to his flight time. The other 199 travelers would suffer no health effects. So the chances that Stuker is the specific 18-million-mile traveler who would be so unlucky is quite small. Stuker was logging more air hours per year (greater than 2,000) than most pilots typically log (<a href="http://work.chron.com/duty-limitations-faa-pilot-17646.html">under 1,000</a>). So these airline workers would have risk levels proportionately lower than Stuker’s. But what about you? If you want to know your personal cancer risk from flying, estimate all of your commercial airline miles over the years. Assuming that the values and parameters for speed, radiation dose and risk stated above for Stuker are also true for you, dividing your total miles by 3,700,000,000 will give your approximate odds of getting cancer from your flying time. For example, let’s pretend that you have a mathematically convenient 370,000 total flying miles. That would mean 370,000 miles divided by 3,700,000,000, which comes out to be 1/10,000 odds of contracting cancer (or a 0.01 percent increase in risk). Most people do not fly 370,000 miles (equal to 150 flights from Los Angeles to New York) within their lifetimes. So for the average flyer, the increased risk is far less than 0.01 percent. To make your exercise complete, make a list of all the benefits that you’ve derived from your air travel over your lifetime (job opportunities, vacation travel, family visits and so on) and go back and look at your increased cancer risk again. If you think your benefits have been meager compared to your elevated cancer risk, maybe its time to rethink flying. But for many people today, flying is a necessity of life, and the small elevated cancer risk is worth the price.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/78790/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/timothy-j-jorgensen-239253">Timothy J.

Travel Trouble

Victim identified after plane hits deadly turbulence

One man has died and dozens have been left injured after a Singapore Airlines plane encountered deadly turbulence, and was forced to make an emergency landing. The flight was travelling from London to Singapore - a route frequently used to continue on to Australia and New Zealand - when the plane hit an air pocket while flying over Thailand. The unexpected and extreme turbulence caused the plane to drop over 6,000 feet in a matter of minutes, sending passengers and cabin crew flying around the aircraft. While dozens of people sustained injuries during the terrifying ordeal, authorities said that one elderly man had suffered a heart attack when the turbulence hit and had died onboard. British media named the man as Geoffrey Kitchen, a grandfather and amateur dramatics performer who was on his way to Australia with his wife for a six-week holiday. The 211 passengers - including 56 Australians - and 18 crew on board were diverted to make an emergency landing in Bangkok after the turbulence hit, just a few hours away from their destination. Kittipong Kittikachorn, general manager of Thailand's Suvarnabhumi Airport, confirmed in a press conference that seven passengers were severely injured, and 23 passengers and nine crew members had moderate injuries. Sixteen with less serious injuries received hospital treatment and 14 were treated at the airport. One passenger, Jerry, recalled hitting his head on the overhead lockers when the turbulence hit. "My wife did (hit her head too), some poor people were walking around, ended up doing somersaults," he said, adding that his daughter was also injured and would likely stay in hospital for "a few days". "It was absolutely terrible. And then suddenly it stopped, and it was calm again, and the staff did their best to tend to the injured people." "There were a lot of them, and some of the staff were injured themselves." Another passenger recalled the moment the aircraft had begun “tilting up and there was shaking”. “So I started bracing for what was happening, and very suddenly there was a very dramatic drop,” 28-year-old Dzafran Azmir said. “Everyone seated and not wearing seatbelt was launched immediately into the ceiling." “Some people hit their heads on the baggage cabins overhead and dented it, they hit the places where lights and masks are and broke straight through it.” Singapore Airlines said the nationalities of the passengers were 56 Australians, two Canadians, one German, three Indians, two Indonesians, one from Iceland, four from Ireland, one Israeli, 16 Malaysians, two from Myanmar, 23 from New Zealand, five Filipinos, 41 from Singapore, one South Korean, two Spaniards, 47 from the UK and four from the US. In the hours after the traumatic event, Aviation consultant and pilot Tim Atkinson shared his theory on what caused the “very significant” incident. Atkinson told the BBC that in the increase in air turbulence can be linked to climate change, saying “it’s fairly clear” the Singapore Airlines flight “encountered atmospheric turbulence”. He also noted that the area — called the Intertropical Convergence Zone — is “renowned among pilots, and I dare say passengers, for turbulence”. “Despite abundant caution occasionally, there’s turbulence ahead which can’t be identified, and the unfortunate result of an encounter is injury and, very rarely, fatality,” he said. Mr Atkinson also noted that the larger the aircraft, “the worse the atmospheric perturbation, the disruption in the smoothness of the atmosphere, needs to be to cause major problems”.
