The reason the Middle East developed into such a large hub for Europe-Asia operations is their plentiful, reliable and cheap supply of aviation fuel.
Whilst Nigeria has plenty of crude oil, it doesn't have plentiful, reliable and cheap aviation fuel - for the reasons alluded to by Capetonian.
I agree with Capetonian also about aviation in Nigeria (I work there) - it is staggeringly backward and bureaucratic and there is no appetite here to make it better. It is not possible even to file online flight plans - the procedure is queue up once for an invoice, queue up again to pay ($US200) and get a receipt, queue up again to hand in the flight plan to the AIS office, pay again for them to make photocopies of the receipt - then thereafter nothing happens. Radio up the tower and they will not have the flight plan. Thereafter, en route nobody has a copy so you have to give every controller all your flight plan details (type of aircraft, departure, destination, persons on board, endurance etc). If you try to suggest how to make it better, they will accuse you of being an arrogant Oyibo and that is not the way we do things in Nigeria.
