"For clarity purposes Off_The_Street, i assume that you agree with PM's conclusion?"
Yes, and I have been saying that for over three years. I am not a structural engineer, but as a logistics engineer I have taken the usual
slate of strenght of materials, heat transfer, statics, and dynamics; and although I might not be able to calculate impact stresses without opening my
Marks' Handbook, I know enough to realize that the scenario that was released for both the WTC and the Pentagon makes sense from an engineering
"That jet fuel burning at max temp of 1200F, combined with "the stuff" burning inside the WTC increased internal fire temperatures to
"For this theory to be true, it implies a vast/ready source of oxygen allowing the temperature of the internal fire to increase. The only ready
available source of oxygen would be the large impact cavity left by the plane impact, thus the results would draw out inferno fires burning at 1800F
due to its limitless supply O2."
Probably. Again, I'm not a structural engineer (nor is anyone on this board, probably); but when you have whole banks of elevators whose
walls were probably breached, you end up with great big venturi columns which can suck up that ground level air and feed the flames, threby raising
the temperature to the softening point -- and thus failure mode -- of the structural steel members.
Note, by the way, the the melting point of steel is not the key factor; it is the softening point and failure-mode point, which is
probably substantially lower. Your comment, "...hydrocarbon fire released enough energy to melt steel." while possibly correct, is
And remember, if there're fires burning at 1800 deg F in one location, that doesn't mean that the entire structure is at 1800 deg F. As a
matter of fact, given the superabundance of oxygen feeding the fires at the center core of the building brought up by the elevators shafts, you'd
expect the fire to be the hotter there (which, by the way, is where most of the structural supporst is). This would account for the fact that
the people at the outer areas by the windows weren't roasted, and why the center support collapsed.
And finally, on a personal note, I find it hard even today to describe -- and I know it is impossible for you to understand -- the rage that everyone
at work felt. The aircraft were Boeing aircraft. Those sons of bitches stole my airplanes to do their deeds.
