I just can't imagine two buildings collapsing like that from damage to the top of them. It looked just like a demolition. People reported hearing explosions and seeing bombed out floors and lobbies well below the impacted areas.
A lot of those people mysteriously died afterwards.
Enough to know that the only thing that causes a massive building to freefall is a controlled demolition. Otherwise buildings would just be set on fire without explosives.
How many other buildings around WTC 1,2, and 7 fell like that?
Oh yeah, none.
