Big place francophone Africa - the last picture reminded me of a couple of places in Angola but that's not French. The design looks late 60's early 70's and remarkably small for anything constructed by ADP or by a "Father of his People" leader - which is the default setting in those parts.
Does it still look the same now?
"Airport " rather then "Aeroport" ........... very interesting
The only place I can think of where you get a French/English mixture is Cameroon - which was merger of UK & French colonies - Yaounde is an International Airport" and Kriti is an Airport as well I believe.............................
