Of the 568 U.S. plane crashes between 1980 and 2000, more than 90 percent of crash victims survived!
The most important thing is not to panic. Panicking can lead to mistakes like not remembering to release your seat belt or not waiting to be out of the plane before inflating your life vest. Also remember to stay low in a fire to avoid smoke inhalation, and don't try to rescue your carry-on bags!
Airlines refer to the first 90 seconds of a crash as "golden time". If you stay calm and move out of the plane fast in the first 90 seconds, you're in the clear.
