Advances in science and technology now mean that over 90% of plane crashes have survivors.
(Recently the FAA and the CAA changed their instructions for the “crash position”. Instead of sticking your head between your knees you should now cross your hands on the seat in front of you. Put your head against your hands and stay in that position for as long as it takes to get to the ground.
Seemingly the key to survival is to get out of the plane as fast as you can. In fact the FAA says that flight crews should be able to evacuate an entire jet in just 90 seconds, because the first minute-and-a-half after a crash is considered “golden time” by many in the industry.)
