I retired from construction after 35 years and they see both sides of the coin but what you guys are missing is the following. Aluminum is superior for cladding buildings, but has no structural integrity when it comes to the actual strength of the building. It adds to the integrity, but the structural steel, rebar and concrete is what gives those buildings its strength. There’s no way in the world that jet fuel will burn at a heat high enough to melt the steel. There were charges set in that building using thermite which develops extreme heat that will make steel melt. In my opinion, saying that the aircraft brought down all the buildings in Manhattan on 9/11, is like saying, John F Kennedy wasn’t assassinated by the CIA… I don’t see how anybody of rational mind can argue that there was no aircraft that ever struck the Pentagon. All of this is just as absurd as the government not knowing where that cocaine came from in the west wing last week.
