In 1997 when we were preparing to deploy the A-Jets to Sierra Leone, the pilots for the Sierra Leone operations were drawn from Kano, Yola and Kaduna and were made to undergo some recurrence and simulated combat training missions at 99, Air Combat Training Group in Kainji. On one of such recurrence flights, Okejuju and I flew to Kaduna to practice some instrument approaches and landings. On arrival at the Kaduna military airfield, we commenced the usual approaches and after about three of such approaches, the Air traffic controller called to inform us that our exercises were disrupting the flying operations of the student pilots who were equally training with the air beetle aircraft. He subsequently instructed that we vacate the airspace for the young pilots and come back after about 25 minutes. In his words: "Aggressor 01, please work northwards and return to continue your approaches after twenty-five minutes". The call sign. Aggressor 01 was always reserved for the Commander of the unit or whoever was the Air Component Commander.
