An interesting theory about this plane is that it's possible it was meant to his Building 7 in New York
Mental gymnastics or not, that is patently absurd. Happened 3 times, in one day - 2 of said buildings were SPECIFICALLY DEISIGNED with the possibility in mind of a collision from an airliner. In fact it was designed to withstand multiple impacts from a 767 (larger than a 747) as a safety redundancy. The architect himself said so. The idea the top portion of the building can warp and crush and obliterate into dust the rest of it underneath is also fantasy.
Despite its long history as a fire safety measure in buildings, evacuation did not become a prominent topic of discussion until the September 11, 2001, attacks on the World Trade Center (WTC). Even with the events of September 11, widespread calls for reconsidering evacuation procedures for large high-rise buildings came mainly from advocacy groups such as the Skyscraper Safety Campaign (SSC) (www.skyscrapersafety.org).
9/11: A SPECIAL 10TH ANNIVERSARY REPORT
Following the terrorist attacks of September 11, NFPA launched a widespread effort to strengthen codes and standards for first responder safety, the built environment, emergency preparedness, and more. Ten years later, those efforts continue — and they’re making America safer.
Madrid Windsor Tower
Dr. Pal Chana of the British Cement Association demonstrated the relative likelihood of floor collapse in a steel versus concrete framed building, using the vivid example of the Madrid Windsor Tower fire which raged over 26 hours on 14-15 February 2005. This former landmark office block of 30 storeys featured a concrete core throughout, but with concrete columns up to the 21st floor and steel columns between the 22nd and 30th floors. Remarkably, despite the intensity and duration of the fire, the concrete floors and columns remained intact however, the steel supported floors above the 21st floor collapsed, leaving the concrete core in-situ and exposed.
