EDIT: I believe bombs were planted in the basements of each tower, sort of like a controlled demolition. I'll put up some videos of witnesses and firefighters stating they heard bombs before the buildings came down.
Do people know psychology?
A got damn building was coming down and you believe people in the middle of it? Not even taking into account that people are in high states of thought and primate fear.
I love my ppl in New Orleans, but, I don't believe they were hearing bombs.
Those levies were in disrepair since the 70's.
Eye witness testimonies have been show to change overtime for the same event by the same people.
