Do you think 911 was a controlled demolition if yes why did the towers fail where the plane hit and not the bottom?

Answer 1

There was no controlled demolition. That was made up by people who want to discredit the US Government. Controlled demolitions (from footage I've seen) start from the bottom- which Conspiracy Theorists conveniently ignore. There where NO traces of thermite [sic], despite claims to the contrary by Conspiracy Theorists who claim that burning jet fuel would not cut through the steel. However, the steel did not need to be cut through in order to cause a collapse, it only needed to be significantly weakened- which is what the burning jet fuel did. I won't go into the physics and science of it, but if you are interested, there are thousands of FACTUAL websites that discredit the Conspiracy Theories, who in fact resort to lies, misquoting people and actually claiming that people said things they in fact DID NOT. According to some Conspiracy Theorists, "someone" supposedly planted explosives all through the building prior to the attacks, without being noticed by anyone. They all appear so surprised that two buildings, built at the same time in an identical fashion should collapse in the same way after such an incident, without further human 'intervention'. Perhaps they haven't seen documentaries on the building of the WTC Towers, they clearly indicate that a great number of corners were cut to save costs. The steel was more or less like huge pieces of puzzles. If they are looking for someone to blame for the manner in which it collapsed, perhaps they should research the building of the Towers first.

Answer 2

Most experts agree that the collapse of the Twin Towers on 9/11 was primarily due to the impact of the planes and the ensuing fires, not a controlled demolition. The buildings were not designed to withstand the impact and heat generated by the jet fuel at the upper levels, which weakened the structures and eventually led to their collapse. The buildings did not fail at the bottom initially because the impact and fire damage were concentrated at the higher floors where the planes hit.
