Yankee,
It's now page 25 and the only specific math I've seen from you attempting to show a 757 could not have made this crater is your color-coded diagram. Since you now concede that diagram does little to disprove anything, what other physics, numbers, do you have? All I see from you so far is "since missiles could have done it, F93 could not have done it," which is a logical error. The other thing you say is, it doesn't look right to you. That's personal intuition, not logic, math, or science. Can you please give us the SCIENCE that conclusively refutes a 757 impact for Shanksville?
Other crashes that left wing prints I can think of two off-hand: Air New Zealand F901, if I recall, left a pronounced stamp of its wing in the ice. And BEA flight 706 (Oct 2, 1971) also left wingprints. If you want an example of a plane burying itself, you can't do any better than Northwest flight 710. After the wings separated in flight, the fuselage dove into the soil and completely vanished. The entire thing. All under the soil.
regards,
Chris
