building 7 has been covered extensively. I posted a note about it earlier. It was meant to be demolished on 9/12 but due to the event happening, they only demolished it two weeks later. They also invited the media to set up and film it down the street. The building was cleared out, and had been cleared out weeks prior to 9/11.
Jet fuel can easily weaken steal beams, let alone the force of the impact, the design of the building and the floors above the impact zone. The floors were riveted on to the sides and the only "steel beams" that existed was in the core of the tower. The fires burnt for over one and a half hours at full intensity before it buckled and layered.
It's been what, 23 years? 100's of thousands of independent investigations, engineers, operators, black sites, Guantanamo and all this and yet you still believe the US government was competent enough to pull this off whilst being incompetent in almost every other aspect.
Critical thinking is a skill.
