I don't mean to dissapoint all the reptoids believers but PBS' Frontline did an Emmy Award winning documentary called 'Why The Towers Fell'. Imagine that, they actually talked to the engineer who designed the building and not their 'friend the structural engineer'. The impact and collapse were fully explained. It was a fascinating documentary and they will be doing a follow-up story on September 5.

In a follow-up to the Emmy Award-winning documentary "Why The Towers Fell," NOVA looks back at the events of 9/11 and reviews the major investigations into the collapse of the World Trade Center. What did the Twin Towers' catastrophic fall teach us about how to improve the construction and security of our most important structures, both present and future? What challenges face architects, engineers, and builders? What obstacles prevent them from adopting new building codes? The film features incisive interviews with key investigators and engineers, including Leslie Robertson, who engineered the World Trade Center towers and takes viewers to the construction site of his current project in Shanghai, touted as the world's tallest structure.
Here's what you'll find on the companion Web site:

Outfitting Firefighters
The firefighters that raced up the stairwells of the doomed towers carried several dozen pounds of equipment, everything from axes and turnout gear to thermal imaging cameras and self-contained breathing apparatuses. In this feature, prepare firefighters for a high-rise response.
