The collapse of WTC 7 is the real ‘killer’ evidence in the arsenal of the 9/11 truthers. No plane hit it and of all the seven WTC collapses, its collapse does appear very superficially, to be somewhat similiar to a controlled demolition. However, it soon becomes obvious under closer oberservation, that this is not the case.
When WTC 1 & 2 collapsed downwards, a lot of rubble and burning debris was driven outwards, horizontally with such force, that it instantly demolished WTC 3,4,5 & 6 and badly damaged the south side of WTC 7 and set it on fire. (see picture and diagram below)
