Effects of a High Speed Crash
This is what happens to a plane (F4 Phantom jet) striking an impenetrable barrier at 500+ mi/hr. A plane moving at this speed has 25 times the kinetic energy of a plane moving at 100 mi/hr. All that kinetic energy must be dissipated by the time it comes to rest. The results are not intuitive. In the case of a passenger plane hitting the pentagon, or a plane hitting the ground at Shanksville PA, if it is traveling at the same speed it has the same kinetic energy per kilogram of mass. Therefore the same degree of destruction is to be expected. This is the major fallacy of exercises such as “Hunt the Boeing” at the Pentagon. Look at this video then I invite you to “Hunt the Phantom”
