5 Capt. Russ Wittenberg on the 911 pilots
"I flew the two actual aircraft which were involved in 9/11; the Fight number 175 and Flight 93, the 757 that allegedly went down in Shanksville and Flight 175 is the aircraft that's alleged to have hit the South Tower. I don't believe it's possible for, like I said, for a terrorist, a so-called terrorist to train on a [Cessna] 172, then jump in a cockpit of a 757-767 class cockpit, and vertical navigate the aircraft, lateral navigate the aircraft, and fly the airplane at speeds exceeding it's design limit speed by well over 100 knots, make high-speed high-banked turns, exceeding -- pulling probably 5, 6, 7 G's. And the aircraft would literally fall out of the sky. I couldn't do it and I'm absolutely positive they couldn't do it."
