My family have been in the explosives industry for years. and the building game for years. and i have many friends who build skyscrapers...currently in Dubai.
Personally, I have limited knowledge, certainly not an expert....however my peers are imo.
Some points.
Many of the people at the site said they felt the ground shaking well prior to the collapse......explosive detenation is the only thing that can explain that.
To induce an implosion, explosives are set to break the steel columns, and some of the columns were in fact broken.
Fire cant make cuts in steel.
Steel melting point is about 1300c Jet fuel melting point is 360c
yes some other things, carpets, paper, and even the magnesium in the aircraft can increase the heat and cause the steel to weaken, but not drop like it did in seconds.
Fire can melt or weaken steel.... yes
Steel columns do in fact expand at both ends when enough heat enters which also makes steel bend or sag.
The paper and other articles coming out horizontally from the floor levels were caused by explosions in the opinion of my peers.
They believe that detenators were let off not only at the base of the buildings, but high up to encourage the collapse.
This caused the implosion which allowed the building to drop and land right on its footprint, which is remarkably unbelievable if it was to happen naturally, as one side would always be weaker than the other if it was the steel weaking only.
So the peers tell me....gotta love the theories. ' Personally......I think the Israelis planted the explosives....and Bin Laden has FA to do with it.
But hey....gotta find some reason to go bomb an oil rich country I guess.
have they found those WMD yet?
Gee Bush reading books to kiddies the day it happens....how convenient I say.
And even after being told continud to sit there.....wonder why?
