Kinematics is only part of the problem with an airliner in a trajectory. There is a HUGE difference between throwing a ball at 20 miles per hour and a 747 travelling at 400 mph. If what you claim is true then it should be physically impossible for a pitcher to throw a curve ball. "Yet It Moves"...... Likewise, if what you say were true, then it should be physically impossible for lifting body vehicles to fly through the air. They should drop like bricks.... but they don't. If what you say were true, then a car traveling down a rain soaked higway at 70 mph should not hydroplane. Yet it does. If what you say were true, then a kite should not fly. For gods sake it isn't even moving!!! Its majic, oh my gawd Ian you've made the discovery of a lifetime!! Kites work by magic!!!

I can dispute those numbers. If the plane is moving at 400 mph and suddenly begins to climb, it will translate a large percentage of its velocity to lift, and the remaining forward velocity to drag (aerodynamic and gravitational), as it climbs. It will top out within 5 seconds it will have gone around 2000 feet at the very least. The fact that its engines were still running would also have added thrust to the vehicle, which would have added the remaining thousand feet to the climb, especially considering that the engines had just been releived of 10-15% of the load put on them by the nose previously (of course there is also the drag of having an open front on the fuselage which could potentially add more drag than is saved by the reduction in weight)....it would add altitude as the forward section reached the top of its zenith, with airspeed dropped below 100 knots...
I think you or someone is leaving out a zero from Zehr's analysis...

Listen buddy, the math doesn't lie. I'll reveiw the video again tonite, but as I recall, they did not specify what part of the plane hit first, just that the first parts did hit at 29 seconds...And I don't care about the 'woe is me... I'm just a martyr for truth' routine....
