I told my guys more than 30 minutes before the first building collapsed that it was going to come down; and I'm just an unsophisticated, rural Tennessean. I was walking out to the flight line when they called me back to the office to telll me it had just collapsed.
I then stated the other one was also going to fall but I stayed to watch it. By the time I returned to the aircraft, the airspace was closed. Bad day for all of us.:(
I don't understand why people can't get their minds around this simple fact. The buildings fall at the speed of Gravity Jesse because that is how gravity acts on every object.
They fell because there are three primary materials that work together in a tower that have a synergy; Glass/concrete/ and steel. The glass went immediately. The steel and concrete baked in >2000 degree heat until the steel softens to a point that it sags. It cannot support the massive weight because the glass is gone, the concrete is cracking, and the steel is compromised. Gravity then acts on the weight and it falls.
The combined weight of multiple floors falling onto the lower floors makes those floors collapse to the subsequently lower floors with an ever increasing weight added.
If a simple rural Tennessean from flyover country can understand this, why can't those oh-so-sophisticated liberals?
