Of course!
The amazing thing is that to create this mysterious missile-firing-missile-cum-fake 757 it would have taken an immense force of hundreds - if not many thousands - of scientists, designers, engineers, aeronautic experts, missile experts, ballistic experts, workmen, ground staff, control tower staff, pilots, camouflage experts and transportation specialists.
I'd imagine that one or two of them may have been a little put out when they discovered that their work was being used to blow up large chunks of New York and slaughter their fellow American citizens in an attempt to kickstart a (now) increasingly unpopular war in Iraq.
Yet not one of them has uttered a peep!
You'd also think American Airlines might have a thing to say about what happened too, seeing as they lost their aircraft and their profits collapsed post 9/11, but they haven't said a thing either!
And then, of course, there's all the thousands of other conspirators involved in the miraculous disappearance of the other planes and - presumably - the cold blooded murder of their fellow American citizens. Once again, the roll call of people involved in such a monumental cover up would be absolutely immense, but - again - not a peep from any of them has been heard!
