What happens when an airplane hits a concrete wall?

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.

The poor pilot

[organboi]

Shitty. Incomplete vid. Not to be compared to 9/11. This is debunker crap.

This was an experient, the small plane hit the reinforced wall at full speed at a 90 degree angle, if a large jet were flown into the pentagon, chances are it would not have been going anywhere near that speed, it would probably not have it a solid surface at a 90 degree angle, the walls of the pentagon are not reinforced as much, and the plane is much larger, and would, all other factors being favourable, have been much harder to vaporize.

nothing just completely vaporizes, that is non sense. Google search: rumsfeld 2.3 trillion - rumsfeld flight 93 - september clues - Former 9/11 Commissioner admits missile hit the Pentagon - you see Rumsfeld leaked his "shot down the plane over Pennsylvania" and Tim Roemer said Missle Airplane on accident because he attempted to cover it up, Rumsfeld did not attempt to cover it up, WHY? Because there was no planes. Google search: YouTube 911 Fake False Clues Flight 93 pt 1/3 (2/3) (3/3)

[theochelpdesk]

tell me your not that stupid and think they are using an engine of an F-8 in the video? There is no engine in the test, if you notice its on a dolley, look where the flames are coming from... Real simple just google search "september clues" watch the video, get the answers to a lot of this non-sense. Follow the money, who made money? Google search Rumsfeld 2.3 trillon. people need to wake up.

The point here is that on 9/11 we were shown jets making huge holes in steel reinforced concrete but the steel/concrete prop here in this real video remains intact while the jet is vaporized.

I thiink this is a bunch of hoooplaaah
