Why does no one survive in plane crash?

Many plane crashes are, in fact, survivable though it s true that some are not. The main thing that makes some plane crashes unsurvivable is speed. Planes travel at tremendous speeds, often several hundred miles per hour. A direct impact at such speed will kill a person instantly. The greatest number of crashes occur at takeoff an landing. A plane that is taking off for a long trip is carrying a large amount of fuel, so a crash could result in a large explosion.
