They have to do with torque of the unbalanced airplane, with its extremely aft-of-center CG, operating on the moment of inertia of the noseless craft. The tail balances the nose, and when the nose falls off, the tail tips down like a seesaw, which (rapidly) increases the angle of attack.
Which, by the way, checks with what the witnesses saw: the plane stopped "like it hit a brick wall" and the remaining pieces fell ballistically from there, albeit with some remaining forward velocity.
Whatever you believe about physics, can you explain why the eyewitnesses were never allowed to speak in any official forum, why the CIA produced its video, or why many of the witnesses and some of the family members, are extremely upset about the TWA 800 "investigation"? I can.
I understand that, but where did they come from? Who did them? What assumptions did they make? What agenda did they have?
