Ive got a question about the flights on 9/11?

well its depressing to say the least, as soon as the planes hit the towers there was a huge explosion, it was like any other crash, only the wheels and a few pieces of metal came out the other side, but it depends for both towers as the planes hit at different spots. I walk past ground zero most days its maad depressing still after all these damn years. The new One world trade center will never match up to the twin towers
