Same gulley that claimed a DC-9 in 1978.
I've been watching for some time and it appeared the initial fire started in the tail - is there a fuel tank there ?
Looks completely engulfed now but there ought to have been time for an evacuation, let's hope so. I don't think ambulances would be able to get down there and the survivors would be led away on the other side from what the feed is showing. Fingers crossed.
