Take a look at this clip and you'll get a good feel for what happens to an airplane when it hits a concrete wall. Many of you have seen the Michael Moore-esque website that asks the question: "If it's true that a Boeing airliner hit the Pentagon, what happened to all the parts of it? "Why did we not find more pieces of it? Where did all that mass GO?" (Therefore, 9-11 must have been a US gov't conspiracy!) Well, for those who question what happened to "all the mass of that airplane"...watch. It's an Air Force engineering test of a concrete barrier, that was to surround nuclear reactor domes, to see if it would indeed survive an aerial attack. With the highspeed cameras rolling, they accelerated an F-4 Phantom to 500mph and... "What happens when an 'Unstoppable Force' meets an 'Immovable Object'???" Watch in slow motion as the F-4 turns to vapor.
