After the Nigerian aviation market was liberalised in the early 1990s, many private airlines emerged and the Bac 1-11 became one of their favourite aircraft. Kabo Air and Okada Air were the largest operators and served many airports for relatively low fares. In 2002 the Bac 1-11 was banned in Nigeria after a couple of ghastly accidents in which the aircraft was involved. Many of the airlines went down and the Bac 1-11s were stored at airports around the country. Most notably in Benin, where derelict aircraft can still be seen around the old Okada Air hangar.
A comprehensive list of Bac 1-11 operators in Nigeria can be found here. All of them were second-hand aircraft, although in 1970 a Bac 1-11 was painted in Nigeria Airways colours for demonstration flights. The national carrier never ordered the aircraft.
There is a picture of a Shorts SH-330 (5N-AOX) in the Okada Air colours, with additional ‘Niger Express’ titles. I cannot recall any sighting of this aircraft in Nigeria – just as of this DC-10 (5N-OGI) in Okada Air colours.
Okada Air was the biggest privately owned airline in Nigeria so far. It popularised air travel in the late eighties and early nineties of the 20th century, operating a huge fleet of BAC 1-11s and B727s. Most of the aircraft are still stored at Benin Airport today. Its owner wrote a short history about the airline.
