Flew many times to Lagos 76 - 79 (BCal 707). Used to stay at The Ikeja Arms - the hotel with the whispering hedge (another story)and The Hungry Man restaurant. I remember at least 2 stories. Rumours of course.
1. A Nigerian short haul flight was on route Lagos - Accra. The stewardess rushed on the flight deck and said there was smoke in the rear galley. The captain sends back the f/o to have a look. He doesn't return so the captain leaves the flight deck to see what was happening. The aircraft hits a little turbulence and the flight deck door shuts. It is self locking! The aircraft passes over Accra out to sea before a ground engineer with toolbox asks if he can help. He manages to open the door and the aircraft manages to turn round and make it to Accra just before they ran out of fuel.
2. Nigerian Airways ran a coastal route Lagos - Dakar via Accra, Robertsfield, Freetown, Conakry and Banjul then nightstop. One day the flight (737 I believe) arrived in Dakar. The captain sent the crew to the hotel then tanked up the plane and flew solo to Freetown where he had a girlfriend. Spent the night with her and returned to Dakar in time for the service back to Lagos. You see - flying used to be fun.
