It's a crazy idea, but you might be onto something!
Evil Lizard Govt Official 1: "Shit, those conspiraloons are right on our case and if we don't come up with something soon, they'll know we used disappearing planes, missiles and the CIA Mike Yarwood squadron for the Pentagon hit"
Evil Lizard Govt Official 2: "No problem. Despite having enough technology on hand to produce Speilberg challenging special effects, a bottomless budget and enough time to create the perfect footage of a plane smashing into the Pentagon, we'll just release some crap footage instead. You know, the kind of thing that looks like it was filmed on a car park camera with a frame rate so low it's almost guaranteed to miss the crash"
Evil Lizard Govt Official 1: "Great idea!"
