It's common sense--3 skyscrapers each damaged in very different ways --do not all collapse straight down in the exact same way. You don't have to be an engineer to see that both twin towers should have collapsed in drastically different fashion and by the way -- why is it that most Americans still don't know a third tower collapsed that day ?

They didn't all fall in the same way. The Twin towers fell from the top, down, from above the point above impact, pancaking as it came down. Building 7 fell from the inside first, then from the bottom, as the entire structure went down.
But I understand -- truthers have their own version of reality.
