Did the world trade centers burn in an hour?

Question

I heard that it took 1 hour for the smoke to clear or something like that is that true?

..i was to young to remember.

Answer 1

Give or take a few minutes.Why?

Answer 2

I know I will sound like a conspiracy theorist, but the aircraft fuel was NOT responsible for the complete destruction of the towers.

I reckon that explosive charges were planted in the buildings several days before the attacks.  

Read these articles:

And read up about a guy called William Rodriguez who claimed that he felt explosive charges being set off.  He says he witnessed workmen drilling and moving stuff in the days before 9/11:

Answer 3

I'd say it took longer than that....I can remember there being smoke from smouldering fires underneath the rubble. at least I think that's what I saw in the papers

Answer 4

I think it was the collapse in about one hour.  They continued to burn for days afterward.
