Weeks after an MiG-21 fighter aircraft crashed in Rajasthan’s Hanumangarh, the Indian Air Force grounded its MiG-21 fleet as it undertakes a detailed investigations into the reason for the crash. The aircraft had crashed during a training sortie in Suratgarh of Hanumangarh district in Rajasthan, claiming lives of three people on the ground. While the IAF wants to phase out the MiG-21 squadrons, it has been unable to do so due to delay in procurement of advanced jets to replace the MiG-21s.
