The old 11/9 conspiracy again, eh?
Just one question, then - how else do you expect a building like that to collapse?
To tilt over like a falling tree?
Controlled demolition removes the main structural supports in strategic places causing the building to collapse in a .... well, controlled way.
If you would care to explain how you think the WTC should have collapsed, other than pancaking downwards on itself, then please go ahead and elaborate.
Just because it looks like a controlled demolition, doesn't mean it is.
Next.... radio controlled aircraft (this was in "the film", right?)
This is true. Around 20 years ago, in an attempt to demonstrate a new aviation fuel that 'gelled' upon impact -(to reduce vapour explosions) - a decommisioned airliner was crash-landed to demonstrate the efficacy of the new fuel. The airline industry was unimpressed, and, despite some remarkable measured results, the superficial fireball put investors off and the project was shelved.
However....., stick this footage amidst a load of tosh about conspiracy and 11/9, call it 'secret experiment', and you have mugs like you fooled for life.
