Aluminium explodes at reletively low temps, a chain reaction of materials exploding could do this, chemical reaction to high temps and pressure is another.
ive watched 15 minutes and saw nothing but pro conspiracy theory, The only factual question was explosions on the lower floor, but that im sure can be explain by pressure of the exploding plane being forced down a central shaft and blowing out in the 4 quadrants of the building.
RE: Was 9/11 Really inside Job?
I dont accept that the material was 2000 for 1/2 hour, I dont know enough about the structure to give an informed opinion.I work with material at high temp and cryogenic and have some idea but what Ive seen in the videos says nothing but a plane did this.
