Mid 1970s , my first business trip to West Africa , to save money I went on a charter flight - Dan Air Boeing 707 - LGW/ ACC most of the other passengers were Gahnains , I remember them well dressed in their Sunday best , some even sported. London Underground uniforms , specally pressed for the occasion.

To my joy the flight was delayed for 6 hours so we crossed the Sahara in day light. I have flewn to West Africa many times since usually on AF bit nothing beat that first trip
