Indian Air Force has grounded MIG-21 jet fighters after the recent MIG crash. In that crash three people were killed including two civilians.
The MiG-21 fighter jets were a continuation of Russian jets, starting with the subsonic MiG-15 and MiG-17.
It was in the early 1950s that the development of MiG-21 started when Mikoyan OKB finished an initial design study in 1954.
However, the MiG jet fighters have a poor safety record in the air. As per the data, the MiG-21s were involved in 400 crashes in the last 60 years. At present, the IAF has three MiG-21 squadrons with a total of around 50 aircraft.
