>"Black Hole" situation present if crew turns back relying on visual cues.

Interesting thought.  For those unfamiliar with the phenomenon, there
were a number of early 727 crashes (at least four) which were ultimately
attributed to this problem.

The Lauda 767 had recent, FADEC-equipped Pratt and Whitney PW4000
engines, while the Birgenair 757 had early (probably non-FADEC)
RB.211-535E4 engines, so there's probably little or no significant
similarity.
