No one can be convince with any criminal investigation by "one man's truth is another man's fairytale".
So nobody has ever been mistakenly convicted then - that's a relief to know.
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. All experts in airline disarster investigations, space programs use these physics principles, in fact, all aviation is based on classical physics.
All your physics will only be correct if the starting conditions are accuratley know at the millisecond that the object was dropped and this is not and never will be the case for this event. So it is still just a guess. A SMALL change in aircraft attiutde will make a massive difference to the trajectory. An educated guess is just not good enough you need hard data.
Yes, I got sucked into this by curiosity, refuse to be fooled by either government experts nor consipiracy theories. The result will not be futile, because there are plenty of "first order of approximation data" available, which can be used to paint a rough picture of what happened.
A rough but wholly innacurate picture methinks.
