IAN: Let's recall again that the plane was at REST at the peak of a climb before it fell. Not only is that consistent with basic physics, but review the video to see the peaked jet sit on the peak, attain a negative AoA, and then fall. Trying to get around that is futile. Your 400-mph jet just does not exist!

IAN: Mike, what I said is what I quoted from a physics book, how could that be my discovery? Every basic physics book covers the same fact. Your examples show you need to do more research. The object with initial horizontal velocity strikes HARDER than the one dropped from rest, even as they both strike at THE SAME TIME. The horizontal velocity is translated into the harder strike, NOT into a faster fall.

IAN: That's wild speculation. Jet-engine operation depends upon the proper angle of attack of the relative wind, and thus, to quote an aviation mechanic, "when the engines pitch up the compressors stall and the engine flames out unless laminar airflow is restored rapidly."

IAN: That must be about the fifth errant claim you've used to support the CIA case.

Watch the video again.
