"Blast expert Allyn E. Kilsheimer was the first structural engineer to arrive at the Pentagon after the crash and helped coordinate the emergency response. "It was absolutely a plane, and I'll tell you why," says Kilsheimer, CEO of KCE Structural Engineers PC, Washington, D.C."
Y'see editor, this is where the likes of you just don't get it. He was the first (professional) to arrive at the scene. Yet he says "it was absolutely a plane". That very choice of language indicates that folk were questioning whether it was a plane or not. It had just happened, yet here is a man rebutting conspiracy theorists!!!!
If you could get past your self-delusion, you'd see it doesn't add up. Your call.
