According this - Debre Zelt, Autumn, 1998 г. This MiG-21bis '1087' is one of the examples sent to Israel for general overhaul and an upgrade to MiG-21-2000 standard. Due to the lack of funds, the aircraft was 'only' completely overhauled before being returned to Ethiopia and then used during the war with Eritrea. Another MiG-21 from the same batch overhauled in Israel was '1083', flown by Col. Petros, when this was shot down and captured during an attack against Asmara AB, on 6 June 1998.
