So you don't have video of a missile, what evidence of a missile do you have?
You run from this question like it is wearing a hockey mask and chasing you with a butcher knife.
And if you have no such evidence, then why are your ilk pushing that conspiracy? That's irrational.
And of course, you simply saying 'it certainly wasn't an airplane' doesn't make the dozens of witnesses of an airplane disappear. Or the airplane debris pulled from the building. Or the debris around the impact site. Or the bodies pulled from the building. Or the the autopsies and genetic tests on those bodies. Or the flight records. Or the flight recorder.
This is the folly of Truthers: they're clinging to a conspiracy without evidence AND ignoring evidence that contradicts that conspiracy. So double irrational.
