"From the second witness's position, he could see both ailerons - the hinged flaps on the control surfaces attached to the wing's trailing edge - fluttering at a high frequency." Hard to believe. Eyewitness accounts are known to be unreliable.
And they flutter that much that a witness from 1200ft below can see them moving. Even less reliable. 1200 feet away and he can see both fluttering? Ralph Finch
