The Singapore Airways turbulence incident that has sadly left one particular person useless and others hospitalised has made many people take into consideration the dangers of air journey.
We’ll hear extra in coming days about how the plane got here to drop so all of a sudden on its route from London to Singapore earlier this week, injuring passengers and crew, earlier than making an emergency touchdown in Thailand.
However fortunately, a lot of these incidents are uncommon, and far less-common than accidents from different sorts of transport.
So why can we typically suppose the chance of getting injured whereas travelling by aircraft is increased than it truly is?
How frequent are turbulence accidents?
Turbulence is attributable to the irregular motion of air, resulting in passengers and crew experiencing abrupt sideways and vertical jolts.
Within the case of the Singapore Airways flight, this sort of turbulence is considered a extreme instance of “clear-air turbulence“, which may happen with out warning. There are a number of different varieties.
Flight monitoring information exhibits that the Boeing 777-300ER Singapore Airways flight climbed 300 or 400 toes after which returned again to the cruising altitude of 37,000 toes, killing one and injuring others. So what’s turbulence and the way frequent are excessive circumstances? https://t.co/MGEsQtAe88

About 25 in-flight turbulence accidents are reported to the Australian Transport Security Bureau annually, though it’s thought many extra are un-reported. A few of these reported accidents are critical, together with damaged bones and head accidents.
Passengers being thrown up and out of their seat throughout turbulence is likely one of the commonest kind of head damage on a aircraft.
Different accidents from turbulence are attributable to contact with flying laptops, or different unsecured objects.
In one instance of clear-air turbulence that got here with out warning, cabin crew, passengers and meal trolleys hit the ceiling, and landed closely again on the ground.
Critical accidents included bone fractures, lacerations, neck and again strains, a dislocated shoulder and shattered tooth. Nearly all of these significantly injured didn’t have their seat belts mounted.
The loss of life of a British man and accidents impacting dozens of others on a Singapore Airways flight that hit extreme turbulence Tuesday is the newest incident to highlight the potential dangers of flying in uneven air.

However we have to put this into perspective. Within the yr to January 2024, there have been greater than 36 million passengers on worldwide flights to Australia. Within the yr to February 2024, there have been greater than 58 million passengers on home flights.
So whereas such incidents seize the headlines, they’re exceedingly uncommon.
Why do we expect flying is riskier than it’s?
Once we hear about this current Singapore Airways incident, it is completely pure to have a powerful emotional response. We’d have imagined the phobia we would really feel if we have been on the plane on the time.
However our emotional response alters our notion of the chance and leads us to suppose these uncommon incidents are extra frequent than they are surely.
There’s a huge physique of literature addressing the quite a few elements that affect how people understand threat and the cognitive biases we’re all topic to that mislead us.
Nobel Prize-winning economist Daniel Kahneman covers them in his bestselling e-book Pondering, Quick and Sluggish.
He describes the best way we reply to dangers is just not rational, however pushed by emotion. Kahneman additionally highlights the truth that our brains will not be wired to make sense of extraordinarily small dangers.
So a lot of these dangers – akin to the possibility of significant damage or loss of life from in-flight turbulence – are laborious for us to make sense of.
The extra uncommon an occasion is, and this was a really uncommon occasion, Kahneman says the extra impression it makes on our psyche and the extra seemingly we’re to overestimate the chance.
In fact, the extra uncommon the occasion, the extra seemingly it’s for it to be within the media, amplifying this impact.
Equally, the better it’s to think about an occasion, the extra it impacts our notion and the extra seemingly we’re to reply to an occasion as if it have been more likely to happen.
How can we make sense of the chance?
One solution to make sense of actions with small, hard-to-understand dangers is by evaluating their dangers to the dangers of extra acquainted actions.
If we do that, the information exhibits very clearly that it’s a lot extra dangerous to drive a automotive or trip a bike than to journey by aircraft.
Whereas occasions such because the Singapore Airways incident are devastating and fire up plenty of feelings, it is vital to recognise how our feelings can mislead us to over-estimate the chance of this taking place once more, or to us.
Other than the stress and nervousness this provokes, overestimating the dangers of explicit actions might lead us to make dangerous choices that really put us at better threat of hurt.
