A look at India’s MiG-21 Bison fleet, the vintage of these aircraft, and the future of their service.

As per information released by the IAF, this was a trainer version of the fighter aircraft with two pilots on board.

As is the norm for training missions, there was one senior pilot, Wing Commander M Rana, on board along with a junior pilot, Flight Lieutenant Adivitya Bal.

The typical mission in such sorties is to impart operational training to the junior pilots and also to test their skills.

The reasons behind the crash are still not known and a Court of Inquiry will look into it.

In the past, Technical Defects, Human Error (Aircrew) and bird hits have been causes of some of the fighter aircraft accidents in IAF.
