It was shooting down of a Pakistani Cessna light aircraft by Indian Air Force Hunter aircraft. There's conflicting information about the date/year of the incident. Does anyone have details like exactly when it happened and other details like exact type of aircraft and its registration ?
Some sources say this happened in 1967 but according to article on indiatimes.com it happened in third week of January 1971.
According to a reliable source the incident happened due to poor visibility conditions (fog ?) during winter in areas near Lahore bordering with India and most likely the pilot of Pakistani Cessna aircraft by mistake entered Indian air space due to poor visibility.
Quoted here is information from article on indiatimes.com.
Abbas"Around the 3rd week of Jan 1971, one small single engine propeller aircraft, allegedly from the Lahore Flying Club, had flown into the Indian territory. Two Hunter Aircrafts were scrambled from the nearest Indian fighter base to intercept this small alien aircraft. This Aircraft was shot down as it did not respond to the messages that were sent to it over the radio, neither did it heed to the visual signal given to it by the pilots of our intercepting aircraft. This set out a high alert in the western sector.''
