On Eid ul Fitr 10 April 1959
An Indian Airforce English Electric Canberra Reconnaissance aircraft was shot down over Rawalpindi.
Because it was Eid al-Fitr most PAF personnel had been given the day off, with only a skeleton crew. The Indian Canberra entered Pakistani airspace while on an aerial reconnaissance mission.
Pakistani radar had detected that an intruder had flown in from Indian airspace. Repeated warnings were issued to the intruder. Two F-86F Sabres from No.15 Sqn flown by Flt Lt. M. N. Butt and Flt Lt. M. Yunis were scrambled from PAF Base Peshawar to intercept it. Flt Lt M Yunis (No.2 in formation) managed to shoot down the intruder at 47,500ft above Rawat.
Both crew members of the IAF Canberra Sqn Ldr J.C. Sengupta, and Flt Lt S.N. Rampal ejected and were captured by Pakistani authorities. They were subsequently released and repatriated a day later after remaining in detention for some time.
