A 1992 report by Sugano et al describes an experiment involving the crash of an F-4D Phangom jet fighter jet into a 10-foot-thick (3.04 meters) concrete block at 480 mph (772 km/h). In the experiment, the fighter is reduced to confetti, leaving no large pieces of debris.
however once building 7 had it's sudden onset of collapse, that's right around free fall. don't give me the bogus count from when a few things on the roof started to collapse. i'm talking when the whole roof started to collapse to the time it reached the ground was around 6.4 seconds if i recall correctly. do the math on that.

@mourantell that's nice, because i didn't say they fell at free fall speed, i'm saying they would amount to free fall had the building beneath the collapse provide no resistance, which apparently it wasn't providing hardly much at all given the constant rate of collapse despite the 'piledriver' force people always refer to was spilling out the sides...there was not enough energy regardless of speed to have crushed the rest of the building without a piledriver force.

@Thrashaero watch?v=qLShZOvxVe4 Do the math, they weren't collapsing at a free fall speed.

what's so hard to understand? the absolute fucking lack of physics!
you can put in caps tons and use big numbers all you want. the numbers of the building's engineering as a whole, for one doesn't allow it to commence collapse quite as suddenly, nor as quickly, regardless how they engineered it for the latter. there was indeed something to slow it down...building beneath. otherwise you're talking a free fall. the kinetic energy in the falling part was bleeding off. no piledriver

@Thrashaero
"ever heard of a building totally obliterating itself in less than 15 seconds?"
What's so hard to understand about a buidling crushing itself? It had a mass of 100,000's of TONS. Once the top portion of the structure began to move, there was no stopping it, or slowing it down.
"ever heard of the fact the building was designed to withstand FULLY LOADED 707's going FASTER than the 767's did? "
Yeah, and the titanic was 'unsinkable' LMAO. NONSENSE

This ladies and gentleman is why Greenpeace is full of shit with their fear mongering about plane attacks against nuclear reactors.
Concrete slab wins!

It was a wall test, dummy.
Do you really think they would learn anything about an old plane.

What's the point in all that, why would they have needed the planes to crash as a coverup when they could have said that terrorists blew up WTC (taking out 1 floor along with support structures would have been enough)

If you want, acept my video response it's another QPhantom Crash
