Scientists and Engineers tell their opinions on the facts of 9/11/2001. I am neither but can easily even as a laymen tell it does not add up. One of the best analyses I heard in this was one lady state, “you cannot have asymmetric damage and a symmetric collapse”. This happened 3 times at the same place, on the same day. If this does not convince you that the official story is BS, you have a mental condition and should be examined by a professional.
