Minimbah Thanks for link. I see the drop, a climb into apparently zero visibility, that if continued the C-130 would have cleared the ground.
The person filming appears to have been able to see the C-130 thru the smoke that is not easily seen on watching the grainy phone video.
The person filming appears to track the C-130 and follows it down to the ground and the fireball first shows when the center of the video is even lower,
he then raises the camera to center on the fireball.
It now appears that the cause was a loss of control due to a loss of visual reference?
If a wing had folded, would that have been evident from the pictures of the ground debris?
