Temo: Re:

Czuch:WTC7 had major structural damage. That structural damage put a high degree of stress on supports for the building. They began to weaken. The question is: Did that structural damage put enough stress on support points so that they eventually gave way. The fires clearly didn't do it. Falling chunks of buildings 1 and 2 ripped into building 7. The fires may have contributed to structural weakness but weren't the main factor.
