Wurm said:Hey Air Amateur, the only one sniffing farts around here is you. You can refuse to accept the reality of the WTC 7 hi-jinx, but that doesn't make the truth any less real. If you think that somehow the fires that existed some 90+ floors up on WTC's 1 & 2 somehow "magically jumped" to WTC 7, when WTC 7 was only what - 47 stories high? - then you need to go back in for further shock treatments.
...and don't forget your Thorazine tab while you're drinking the Kool-Aid.
Were you there? The WTC towers were mostly air until the planes hit, then they became colums of fire, choked of all but minimum air to support combustion, hence the thick, black smoke. When they collapsed, and BOTH started on the floors ABOVE the impact, the air trapped inside along with the heated fuel vapors and gases was forcibly blown out the bottom floors where it ignited when it mixed with the outside air because it was above the flash point. These jets of flame are what damaged the surrounding buildings and caught WTC 7 on fire. You didn't see it because of the dust cloud.
I could go much deeper into the fire science involved but it would overload your feeble mind.
