I've seen a similar show on History Channel or something, in which it was explained just how the buildings collapsed and why it took some time after impact and how the pressure and heat built up to that point. It was pretty clearly and thoroughly explained, as I recall.
Building 7`s collapse was ironically caused by Rudy Guliannis`s stupid decision to place the disaster command center, in building 7.
Going against the advice of most experts and the FDNY heads,Gulliani placed the command center in the very spot that was previously attacked by bin-laden.He was advised to put it across the river in a nondescript location, underground.
He said he wanted to be able to walk to it from Gracie Mansion in the event of a problem.
So,when the towers were attacked,again,his command center became useless.
That`s the reason he was walking around outside like a clown with a dust mask on,with no real means of communication besides hand radios and cell phones,which weren`t working or not working well.
People were saying how brave he was to be walking around outside.That was all he could do,lol,now that the command center was buried in rubble.
Now the command center was a multi floor,multi room set-up.There were living quarters and food/water/supplies for a number of people.There were rooms for the communication equipment,the best money could buy.There were meeting places and storage.
And there were huge diesel generators and huge tanks of stored diesel fuel.Thousands and thousands of gallons.
It was that fuel,placed there by stupid rudy,that feed fires already started by the collapse.
For days the diesel leaked,feeding a fire that otherwise might not have done much.There was so much smoke,steam,dust and vapor rising that it went un-noticed.
The fire doesn`t have to melt the steel to make it fail.The only thing the fire needs to cause failure is to "anneal" the metal,taking away the steal`s heat tempering and it`s strength.
This is a big point for truthers,the claim that a diesel fire couldn`t melt steel,or jet fuel(which is like diesel fuel).Which is true.But is didn`t have to melt the steal,just cause it to lose it`s tempering.A deisel fire set under steal for days,will eventually turn the steel red hot.
The steal during prouction, is treated with heat or stress to create a tempered steal.
Untempered steal is softer and more maliable than tempered metal.Easier to form and work with but to weak to support much weight.By tempering the steal(with heat, then cold) it makes the steal much stronger than without heat treating.
Car chasis are tempered.Without that added step in productio,cars would fold in half under normal use.
If you build a structure with tempered steal and load a lot of weight on top of it,then heat the steal to the point where the steal is annealed,the weight of the loads will cause the steal to bend.
It doesn`t have to be very hot to turn metal red hot,you can do it with a knife in a stove flame.That`s all it takes to anneal tempered steal.

It was this series of events that led to building 7`s collapse.
The new command center was moved off of Manhattan, across the river, under a plain low-key building,like it should have been before 9/11.
