Take an shatterproof glass. Make it to fall from some height. You will see it to break. Put it on the top of a very thin aluminium can. Make them to fall again. You will see that the glass will not break anymore.
Figure 20 glass and can
When the glass without the aluminium can falls, the kinetic energy makes it to be broken. When the glass falls on the top of the aluminium can, the kinetic energy transforms itself into deformation energy of the can. So the impact forces on the glass don’t have the value to break the glass.
In a crash of an airplane, the structures, adequately designed will adsorb the vertical kinetic energy of the airplane. So the deceleration (forces) on human body (inside) will not cause fatal or sever injuries.µ
So passengers and crew could survival even the airplane is destroyed.
