There was a 707 deliberatly ditched in the Nile South of Khartoum by a Sudan Airways crew.
The airplane was on lease from Air Lingus for the Hadj and was returning from its first trip when the power went off in Khartoum. The Irish crew were still in the Hilton after ferrying it down!!
All got out, only crew on board. The story at the time was that the crew got very low on fuel and with no chance of the lights coming back they found the Nile on the radar and landed in it about 15mls South of town.
I flew over it, it was there for a long time and they recovered the engines as I saw them behind the hangar.
It was said that every mud hut for miles had a triple airline seat with seat belts for a couch!!
