An engine piece droped from an airplane can be calculated acurately, without considering wind, air resistance, high school physics will give you the acuracy in the meters, not miles, with educated guess on initial conditions: velocity and altitude.
Nonsense. Like I tried to tell you earlier and like the voice recorder confirms
is that whoever was in control of the aircraft the last couple of minutes,
was pulling and pushing the yoke. It is likely to assume that the aircraft was pitching significantly up/down in that stage. A likely cause for
loosing the engine could have been that too many G's were pulled
(the 757 does not have FBW control laws)
So, here is your highschool physics test.
Assume the aircraft is at 7000 feet. Lets say one engine falls
off. Calculate how far the engine will move before it hits the ground
in the two scenarios below;
a) 500mph, pitch +10 deg in one moment,
b) 300mph, pitch - 20 deg in the next
How close will a) and b) be to eachother? I'm afraid you your
answer will be in KILOMETERS apart.
Unless you have the FDR file, like the NTSB probably has - forget it!
