My readers were kind enough to respond to my post describing my discomfort with the theory that planted bombs brought down World Trade Center 7 and perhaps the Twin Towers. (Scroll down.) My response to (most of) these responses may be of sufficient interest to justify a new post.

"Annealing is done to soften steel, which does not necessarily cause it to lose much of its strength." After exposure to temperatures well below 1500 degrees, a rasp can be shaped into something non-raspy. Many believe that the "transfer truss" design is inherently unstable under the best of circumstances. How much loss of strength is necessary to bring ruin to a design which was poor to begin with?

"I'll note that though some firemen claimed there was structural damage to the building, AFAIK none of them claimed there were diesel-fueled fires." I didn't know that firemen in the process of fighting a fire usually offered opinions as to what caused the blaze.

"A team of researchers at Worcester Polytechnic Institute in Massachusetts studied steel samples from WTC7 and were quite mystefied by their "evaporation" from a high-temperature sulfidative attack. WPI still has an article on its web site "The Deep Mystery of the Melted Steel." The researchers could not explain the source of the sulfur..."If the Worcester Polytechnic Institute is puzzled by the presence of sulfur, I suppose I ought to be as well. Even so, this laymen would like to remind you of the presence of 109,000 gallons of oil, and that the type of oil used in the generation of electricty has (as a little googling will tell you) a notable sulfur content which would be dispersed into the air as the oil burns.
From the
WPI's introduction to the "Mystery of the Melted Steel" study: ""The important questions," says Biederman, "are how much sulfur do you need, and where did it come from? The answer could be as simple--and this is scary--as acid rain."
(To read the rest, click "Permalink" below)4. "Your use of the interchange between Silverstein and the fire chief is itself a quote out of context. We don't have any record, as far as I'm aware, of what conversations Silverstein and the fire department had before that..."
I did quote in context. For quite a while now, bomb buffs have referenced that Silverman quote as though it were the holy effing grail. Now that I've pointed out that this quote doesn't mean what the buffs THINK it means, they say: "Pfft. His words are unimportant."
C'mon, guys. Play fair. This isn't Calvinball -- you can't change the rules as you go along.
5. "Joseph, can you actually find us evidence of an explosion that brought WTC7 down?"
By which you mean, I presume, an explosion involving the deisel tanks. In the first place, the burden of proof is on those positing a conspiracy. (I accept this challenge speaking as one who has posited a few conspiracies in his time.) Second, photographs show that fire broke out on the very floors where deisel tanks were stored. Coincidence?
6. "There is a lot of buzz here in NYC, because major local media are actually beginning to take 9/11 truth issues seriously."
Good. Maybe folks will start to ask about some of the real issues: Who is Magdy El-Amir? Who is Wally Hilliard? Why were the hijackers visiting those SunCruz boats?
But if the focus remains on this bombs-in-the-buildings crap, then I despair. Numbers of believers do not make a proposition true. If 75% of the public believes that a flying saucer crashed at Roswell, does that mean a saucer crashed at Roswell?
7. Every time I ask the "Why bother?" question, the answer comes down to this: "More psychological oomph. People would not have gotten really, really, REALLY scared unless they saw buildings fall."
Cah-mon, folks. Do you really expect me to believe that this posited "oomph" factor justified the drain on the economy and the loss of life?
Okay. Let us posit that someone -- call him Mr. Evil -- pushed a button and set off bombs in the south tower (the first building to go). Why didn't he wait until the building was evacuated?
A conspiracist might answer: "Because it was important to maximize the loss of life! He needed to SCARE people! Oomph! They needed lots of OOMPH!"
Okay. But if that "oomph" factor made it so bloody important to maximize the loss of life and scare people, why didn't Mr. Evil make BOTH buildings go down at once? Why wait until the north tower was evacuated?
"Um...maybe he was SOMEWHAT evil but not TOTALLY evil? Maybe he needed just a certain degree of OOMPH but not too much OOMPH?"
Yes, I know that I've argued with a straw man, which is, I suppose, a very presidential thing to do. I doubt that any real life debater will be able to make the scenario more convicing to me.
