Ask Dr. Science
NPR used to have a short humor featurette in the late afternoon called Ask Dr. Science. Produced by Duck's Breath Mystery Theatre, it featured a (straight) question and a very absurd and amusing, pseudo-scientific answer. The piece would close with "Ask Dr Science, he knows more than you do." (Dr Science voice): "I have a master's degree!" "In science!"
Well, that's the way that I feel about this post. The guy claims to have a master's degree in engineering from Stanford, but look at this claim:
Steel frame towers are built very strongly. They need to withstand the pressure of gale-force winds, the violent rocking motion of earthquakes, and the ravages of time. For this reason, they are almost impossible to destroy.
Airplane strikes do not destroy skyscrapers. A bomber strike to the Empire State Building during World War II did not harm that building. The World Trade Center towers were designed to survive a strike by a Boeing 707. The 767 is more massive, so the building was stressed near its design limits. But if a failure had occurred at that moment, it would have been at the point of highest levered stress, near the base of the tower, and the tower would have fallen over like a giant tree in a forest windstorm. That, of course, did not happen.
What in the world is he thinking? Lord knows, the Deniers make a lot of ridiculous claims, but that just might be up there with the Keebler elves and their tree analogy.
