Gutting out the WTC ready for demolition.
So getting back to the main thrust, regarding the second aircraft. Whatever was or wasn't recorded from the ground (whether by genuine witnesses or plants), the footage originally shown by the (controlled) media corporation/s was fake. Therefore, it was a managed event.
I'll wager that a kernel of an idea for terrorists to fly planes in to WTC, was exploited, nurtured and brought to fruition by American psycopaths.
These sick fxxxs murdered their own people. We do it here as well.
