Question about cars, I want an answer. No more messing around., page 2

My answer: Pyroclastic flow. You've all seen the collapse footage with the thick plumes of downward-heading 'smoke'.

"Pyroclastic flows can only occur when a dense slurry of fine dust is suspended in air or volcanic gasses and is concentrated in a defined area. The suspension will then act as a separate, denser fluid that remains distinct as it moves through the less dense medium. Because of their density such flows can reach speeds of hundreds of miles an hour and do tremendous damage, especially with the high temperatures seen in volcanic events."

So, bearing in mind the fact that immediately following the collapse Ground Zero and the surrounding area was enveloped in a cloud of fine pulverised concrete dust (this is all the debris around the burned out cars seems to consist of), which should have deprived the initial jet fuel fires of oxygen, there were enough SUPER-heated gasses still present to incinerate these vehicles.

The lack of heat damage to the surrounding buildings in the shot with the burned out bus can easily be explained by the channeling effect of these buildings. Pyroclastic flows behave more as a liquid than a gas, and any liquid flowing through a defined channel loses velocity toward the edges of the channel, to the point where the liquid at the very edge is hardly moving at all. In the case of the pyroclastic flow the air would have been far hotter in the middle of that street than at the edge, and there may have been relatively little heat transferred. The cars would have been completely surrounded by the hot gas.

All this, even if accurate (I'm no vulcanologist), still begs the question: how was there enough chemical energy in in two planeloads of jet fuel to bring down two massive skyscrapers and turn the resultant debris into a super-heated slurry?

I don't feel that an EMP could have started the fires.

"...the region where the greatest damage can be produced is from about 3 to 8 km from ground zero. In this same region structures housing electrical equipment are also likely to be severely damaged by blast and shock. According to the third edition of The Effects of Nuclear Weapons, by S. Glasstone and P. Dolan, “the threat to electrical and electronic systems from a surface-burst EMP may extend as far as the distance at which the peak overpressure from a 1-megaton burst is 2 pounds per square inch.”

The reason that a lot of the photos are so remeniscent of a nuclear ground zero, is that is generally the only man-made phenomenon that produces a super-heated-shock wave.

Fortunately, building of this size don't fall down very often, so it is impossible to compare the situation like-for-like with another collapse or demolition. Without that the official line is just as valid, but certainly not more-so, as the alternative theories.

Personally I feel that we are looking at some kind of bomb, and not simply jet-fuel fires. Does anybody remember the bomb they talked about mid-nineties that destroyed buildings without affecting organic matter? It made the news and was never mentioned much after that.
