Hello - I'm new and have joined in hope of finding a conclusive answer about the Third Tower collapse and Shanksville. I don't live in America but the tragedy and loss of 9/11 was heart-breaking. The theory of the US government behind the attacks has continued to be of interest to me and I see the possibility of the Twin Towers and the Pentagon as targets to fuel US citizens into war, however, I have yet to understand why these two other crashes occurred. Why was that particular building targeted as well as the Twin Towers? The deep empty hole in Shanksville is truly a mystery, i.e. where is the debris and if it wasn't an airplane that crashed what happened to the actual plane? Thank you.
