The report I read indicated it had just dropped from the planned 33,000 ft to 31,000, per local air traffic control’s request.
Others will doubtless deny this because it doesn’t fit their agenda.
A prudent person might wait until the facts (yeah, right) come out in the official investigation.
In any event, the black box displayed in the presser yesterday looked fairly intact, it will tell its own tale.
The black box will tell us if it dropped and that would implicate the rebels to some extent. If it wasn’t dropping, then the question remains: why?
