How to Survive a Plane Crash
Your carry-on bag
The safest thing to do with your carry-on is leave it on the plane.
Flight crews ask you to keep your luggage clear of the aisies for a reason; in the event of an evacuation, you don’t want it blocking an escape route.
What to wear
The US National Transportation Safety Board says that 68 percent of plane crash fatalities occur in post-crash fires, not in the initial impact.
Therefore, on the day you’re flying, avoid wearing flammable synthetic fibres (合成纤维) like polyester and nylon. Instead, choose natural materials like cotton or wool. It’s also a good idea to favour long pants (like jeans) and a long-sleeved shirt for extra protection from flames and sharp objects.
Your seat
A Popular Mechanics study of 20 commercial jet crashes with both fatalities and survivors found that passengers seated in the rear cabin had a 69 percent chance of survival, compared with just 49 percent for those in first class.
Besides, exit rows are the safest place to sit on the whole plane. In the event of an evacuation, the closer you are to an exit, the higher the chance you’ll escape uninjured.
During a crash
The safest way to sit during a crash is to brace(支撑) yourself.
In a 2015 crash simulation, Boeing found that passengers who both wore their seat belts and assumed a brace position (feet flat, head cradled against their knees or the seat in front of them if possible) were likeliest to survive a crash.
And the first thing you should do during a crash is put on the oxygen mask the minute it drops. During a loss of cabin pressure, the fall in oxygen can knock you unconscious in as little as 20 seconds.
