The last man out says there were explosions in the basement.
This is from Rosie.com
Update: A friend on IRC asked, "you seriously questioning the WTC was just planes or not?" From time to time I think of the open questions like Silverman’s insurance policy, the assessment that the towers needed to be torn down and rebuilt but was too costly an endeavor, the demolition style collapse of the buildings instead of toppling, and all the other babble from the conspiracy theorists. Now, I love a good conspiracy theory. Conspiracy for 9/11 almost writes itself. When I write conspiracy, it’s just creative writing often for satirical purposes. The truth of the matter is that 9/11 was the second attempt by terrorist to bring buildings down. The first attempt was with 1500 pounds of explosives in the basement in February 1993. Including explosives in the basement is conceivable for an effort that planned to organize 10 planes and at one point included simultaneous attacks on 2 continents before being scaled back to the 4 plans used on 9/11.
The commission found that the plot originally called for hijacking 10 planes and attacking targets on the eastern and western coasts of the United States.
The plot also called for hijacking and blowing up 12 airliners in Southeast Asia, but al Qaeda leader Osama bin Laden scrapped that part of the plan because it was too difficult to coordinate operations on two continents.
Bin Laden scaled back the plot in the United States to the four planes that were eventually used in the attack.
I doubt it though. That day was horrible. I watched it broadcast live and as smoke billowed out from the towers I was amazed they were still standing. But like JFK’s assassination, I think people will believe strongly one way or another and that some questions will never be answered. None-the-less, I found Rosie’s video interesting.
