Respect my existence or expect my resistance
And how many people actually ever even considered the possibility of an aircraft, never mind a passenger plane, flying into a building?
It's all very well saying that architects and engineers should design a building other large structure to cover worst case scenarios, but these will be events that could be REASONABLY foreseen, such as fire, flood, explosion, earthquake, depending on the location of the building. And even though the designers of the twin towers had not forseen that some 30 years after the buildings were erected there would be a side impact collision between the towers and airplanes (who would have, lets face it), the buildings, when they collapsed, failed in the way they were designed to fail in any demolition-type scenario - they collapsed straight down.
What are designers supposed to design for now - alien spacecraft invasion? Vampire attacks? Zombies? Owl god worshippers running amok?
