It now emerges that the C-17A with the 640 PAX was swarmed - not loaded under direction.
Also, there is a video out there taken from inside the aircraft - which I'm not going to link - of a C-17A flying along with a dead body flapping against the closed undercarriage nacelle (part inside).
USAF conducting investigation into what transpired over the past few days - Pentagon spox stated this morning may get update drom USAF today.
