Regarding "9/11 conspiracy gets support from physicists' study" – the article clearly demonstrates how uneducated these physics "experts" are.
1. "67 percent of the strength would need to be lost for failure to ensue, which would require the steel to be heated to about 660°C." A gasoline fire ignites at 495 F and burns at 1500 F. (First point disproved.)
2. "Most high-rises have fire suppression systems (water sprinklers)." One can't use water to put out a gasoline fire – elementary school physics education lacking here.
3. "Structural members are protected by fireproofing materials." Asbestos was used in the lower parts of the building, but not used in the higher parts where the plane hit, because it was considered a "bad material" to use – lack of education on U.S. building practices.
4. Most buildings are not designed to hold the weight of an airplane on top of them, so given all of the above, this point is mute.
The only thing this article proved was just how stupid the European educational system really is.
