And the only accident at Khartoum was in 1959, TG522, engine failure(s) after take-off, crashed returning. 5 Dead (all crew) all pax survived, 25. (As he was thirteen at the time I'm developing a suspicion that he may have been aboard this aircraft, with the details withheld from him.)
My increasingly fallible remaining grey cells, indicate that there was a Hastings that crashed in Libya, El Adem or Idris (Castle Benito), spring to mind. But with similar results. The flight deck crew died and all the passengers survived. This was punted at the time as a great example of the effectiveness of rear facing passenger seats.
