this is 1.5 hours long IIRC I watched this for half an hour - then I noticed that WTC7 started to tilt as it approached the ground - so I guess it was not a perfect symmetrical implosion - it looked the same as the WTC1 fall and the WTC2 fall And I dont have a real problem with the failure of 1 column bringing down an entire building. I dont think that buildings in the USA are designed to withstand a progressive (floor to floor) collapse. I dont know why there was the sound of an explosion. I dont know why there were people saying "the bld is going to explode". Maybe they smelled gas, gasoline, or diesel fuel. Maybe they were repeating a rumor. I did not see any sign of debris shooting out of WTC7 as it collapsed. I did see a photo of heavy fire on the top floor and on a middle floor (with fire showing from multiple windows on each floor). Maybe super heated gases had flowed up thru the bld for several hours and tuned most of the columns to putty. -- You received this message because you are subscribed to the Google Groups "massfire" group.
