ShilohCat,

Thanks for the link to "Muslims Suspend Laws of Physics!".

I've seen that page before, and I find it a curious blend of skepticism, fact and half understood principles of engineering.

One criticism I have of J. McMichael's analysis is that he seems unclear on the fact that structural steel doesn't need to be at the melting temperature in order to lose tensile strength. I find that the explanation provided by the official engineering assessment is quite plausible. That the floor trusses on the levels where the fires burned out of control would sag over time and thereby break free from their point of attachment at the columns. Once this occurred, a progressive collapse became an inevitability.

Mr McMicael also overstates the degree to which the concrete in the structure was reduced to "dust". I've seen footage of the debris sorting facility that was built up at Fresh Kills, and the material was a mix of rubble, with not all concrete reduced to the fine aggregate size he implies.

That said, it is still clear that the FBI, FEMA and others prevented independent investigators onto the site in the critical period immediately following the collapse. The plausible explanation is that they were necessarily attempting to maintain order in a decidedly chaotic situation. The skeptic's position was that a cover-up was being carried out by high governmental officials. I tend to find it hard to believe that a cover-up could have occurred on something of this scope and nature.

However, tantalizing assertions, such as the "pools of molten metal" purported seen at the bottom of the excavation would be clear red flags. Do we have any photographic proof or official analysis of this molten structural steel? Not to my knowledge. OTOH, we also don't have proof that such molten metal actually existed. All I've seen is hearsay.

I'm trying to keep an open mind on the events of 9/11. I'm more troubled by what appears to be fraud with regard to the Pentagon attack, than with the skepticism about how the WTC towers collapsed.
