Having lived in Senegal, while true the population in general may not have flown, aviation has been around that part of the globe for a long time.
Just a couple of examples:
Dakar was an alternate emergency landing site for the shuttle in the early years, in case of a problem after the launch. (vs post mission, before you guys get on me about that one).
Test flights of the Concorde prior to its entrance into service.
Dakar, was a stopover city for the Paris - Rio flights of the AF
When I lived there, airlines that flew there included: Pan Am, Air France, Lufthansa, Air Mali, Air Senegal, CSA, Aeroflot, Sabena, Nigeria Airways, Cameroon Airlines, Royal Air Maroc (which by the way currently flies the 73's, for Air Senegal, and possibly is the majority owner of Air Senegal), Air Afrique, Iberia just to name a few. Since I was fairly young, I may have forgotten a few!
I also remember seeing the remnants of ramps for flying boats, in Dakar as well, so probably it had some sort of flights on those planes, prior to the advent of the jet age!
