Controlled by OBL perhaps.

But it didn't need any explosives, hand-positioned thermate, or the like 
- the burning jet fuel would do that to a building like WTC.

I am a Brit and I don't know crap about WTC7, or the Pentagon, except to 
suggest that if I were the terrorist in charge I'd have attacked the 
White House, Congress, Senate, suchlike instead - but OBL was well-known 
for antipathy to the New York financial world and the US military.

But I do know a lot about metal (and more than enough about explosives, 
and demolitions), and let me tell you, the jet fuel fire woulda done it. 
No need for any explosives.

If a lot of men in black suits or keffiyas did somehow carefully plant 
explosives and/or thermate in WTC (without anyone noticing), their 
effort was wasted.

Actually that would have astonished me - the building weighs maybe 5000 
times more than the plane, and is built to take huge wind side loads. 
Getting knocked over by the plane crashing into it would be like you 
getting knocked over by a pingpong ball.

But after the crash, the thermal protection on the interior steelwork 
had been shattered, and the fuel started burning.

The steel never melted, nor did it come close to melting - but there was 
a lot of fuel, and the whole of two or so floors was on fire. That's a 
lot of heat in one place. The word "inferno" comes to mind.

The temperature in the center of the floor would have been at least 
650C, and more likely somewhere around 700-800C. Even at 650C A36 
structural steel has only 38% of its room-temperature yield strength. At 
800C it would be less than 17%.

How much steel do you think they put into something like WTC? - the 
answer is, a little more than three times what's needed to stop it 
collapsing.


Ever seen a blacksmith work? He takes the steel out of the furnace and 
squashes it with a hammer. It starts off at about 900C, when it's 
glowing yellow and the steel is quite soft, but he will still hammer the 
steel until it is dull red at about 550C, when it becomes too hard to 
squash with a hammer blow.

Hey, would you even think about the possibility of squashing that lump 
of steel at room temperature with a hammer? Yet a smith can do it with 
ease when the metal is at the same temperature as the steel in WTC got to.


Then consider that the inside of the outer steel shell would have been a 
lot hotter than the outside - which would cause the box columns of the 
shell to bend and buckle.

Both the above phenomena, the loss of strength and the bending and 
buckling are well-known to metallurgists, and are easy to demonstrate.

So, no wonder it collapsed.


The straight-down nature of the collapse might seem surprising, but it 
isn't really - take a rod as long as the WTC was high, and tip it over 
slightly. It takes a long time to get moving - but it only took ten 
seconds for the WTC to collapse. There wasn't enough time for it to go 
any way except straight down.

The reason it collapsed so fast is interesting though - one or two 
floors collapsed, then the the top ten floors fell down on the 
next-highest intact floor - which had no chance of withstanding the 
impact. That floor failed immediately, and so the cascade continued.

If I have given the impression that the first floor to collapse 
collapsed all at once, it probably didn't - most likely part of it, 
perhaps a part which had been damaged by the impact as well as weakened 
by the fire, collapsed first; then the uncollapsed part of the floor had 
a whole lot of extra weight on it.

In time this might have tipped the top ten floors sideways - IIRC the 
top floors did tip a bit on one tower, but I haven't seen the film 
recently - but there wasn't enough time for that to develop, the 
uncollapsed part of the floor also collapsed, and the top ten floors 
fell as a lump.

After that, once the top ten floors get some momentum, they go straight 
down; and there ain't nothing underneath strong enough to stop that 
momentum.

So, that's how it would have happened if the fire caused the collapse. 
Seems to me to be pretty much what actually happened.


If it was spies, or terrorists, or demolition contractors, I'd expect 
something different.
