A number of former Nigerian airliners are currently stored at Lasham airfield in Hampshire, England. Lasham is operated by ATC Lasham, an MRO provider mainly dealing with 737s.
Four former Air Nigeria 737-300s owned by various leasing companies await their fate. Between 14 and 16 years old, according to Aviation Week's Intelligence Network fleet database, these aircraft are expected to fly away with new operators in the not too distant future.
Nearby sits a former Aero Contractors 737-500, withdrawn and left open to the elements. At 21 years old, there is no market for this aircraft except scrap perhaps. Aero Contractors still operate a fleet of 16 737s.
A former FirstNation Airways A320 (1993 vintage) looks in excellent condition, and has a high probability of finding a new operator soon. FirstNation took delivery of three secondhand A320s in 2011 but they were only briefly in service before the airline ceased operations.
