From The Olden Days: Bac 1-11s in Nigeria
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.
