The first PAF jet fighter to shoot down an enemy aircraft was F-86F Sabre No. 55-005 of No. 15 Squadron, the unit also known as the "Cobras". Flying this aircraft, Flight Lieutenant M Younis downed an Indian Air Force Canberra while it was on a photo reconnaissance mission high over the Rawalpindi area on April 10, 1959, an Eid day. Pilot Officer Rab Nawaz was the Air Defence Controller on radar for this mission.
