Poway, your truncated quote of Bill Manning in an attempt to pull him into your crackpot theorizing is nothing short of libelous. Here’s what you quoted:
The structural damage from the planes and the explosive ignition of jet fuel in themselves were not enough to bring down the towers.
And here’s what he said next:
Rather, theory has it, the subsequent contents fires attacking the questionably fireproofed lightweight trusses and load-bearing columns directly caused the collapses in an alarmingly short time. Of course, in light of there being no real evidence thus far produced, this could remain just unexplored theory.
The frequency of published and unpublished reports raising questions about the steel fireproofing and other fire protection elements in the buildings, as well as their design and construction, is on the rise. The builders and owners of the World Trade Center property, the Port Authority of New York-New Jersey, a governmental agency that operates in an accountability vacuum beyond the reach of local fire and building codes, has denied charges that the buildings' fire protection or construction components were substandard but has refused to cooperate with requests for documentation supporting its contentions.
Clearly this man was concerned about fire safety, and making sure that a fire-induced catastrophe was understood well enough to make sure it wouldn’t happen again. He’s suspicious of the degree of fire protection that was present in the WTC, but that’s it. In the context of the thread, you imply that he’s a lunatic like you who thinks the buildings were demolished. If you had any sense of decency, you’d delete that post and apologize for it.
