SaNdMaN: Interesting parody, but a completely different scenario unfortunately - a head on collision between two objects of different densities at different speeds is completely different than the weakening/melting of steel with kerosene. It's like trying to compare driving your car into a block of ice with lighting a kerosene fire in the car.

Without another accelerant like Thermite/Thermate to raise the temperature of the fire, much of the metal components will survive, structurally. They won't look too nice, but the car's roof and frame will stay in place(assuming that you have an older steel-framed car, and not an aluminum or other alloy framed car[unless of course your car somehow has a Titanium alloy or Tungsten alloy frame or whatnot, which I don't know of any that do, but it's a nice thought]).

Of course, many cars have plastic based bodies, so the roof itself might not stay in place, but the frame shouldn't have too much of a problem.

Last I knew, the exterior of the WTC buildings were not made out of plastic, so there's really very little chance of a fire causing their destruction.

Actually, they caught on fire before, even, and didn't get destroyed(unless we somehow rebuilt them and I wasn't aware of it).

Of course, now I'm just ragging on you - sure, it's POSSIBLE(through such theoretical physics as Quantum Mechanics and whatnot) that kerosene could have caused the WTC buildings to collapse - making them the first, second, and third steel and concrete buildings to collapse in the recorded history of the planet, but the probability of it actually happening is about the same as the probability of you being able to push your hand through a solid steel plate without any resistance - sure, according to Quantum Mechanics, it COULD happen, but, well, how many times have you leaned up against a building only to find out that your elbow was half-submerged/half-merged with the brick and mortar?

To date, I know of only one person who can achieve this effect - a guy by the name of John Hutchison.

He uses something like 6 or 8 Tesla coils to do it, too, and if 6 or 8 Tesla Coils big enough to surround the WTC complex were around them that day, well then I probably wouldn't be arguing that the destruction of the WTC complex was not caused by just the planes alone...then again, it'd be way too obvious that the planes were not the only causes of their destruction that documentaries such as this one wouldn't be needed....not to mention the power requirement that'd take....lol

So yeah, get a solid steel plate and practice pushing your hand through it - let me know when you're able to, and I'll consider taking some of the things you say seriously. According to Quantum Mechanics, it's possible, and so long as you believe it's possible, well you should be able to prove it, huh?

Have fun!
