As i said earlier, IAF will phaseout Mig21 from service with the crash of last surviving mig21 flying with IAF. Thanks to GOI for the priorities.
In 2012, then defence minister A K Antony informed Parliament that out of 872 MiG aircraft purchased from Russia more than half were lost in crashes. In the last 60 years, more than 200 pilots and 60 civilians lost life in these crashes. So by 2012 400 plus of that fighter jet never got the chance to get retired . Then there is more to add after 2012 . I wonder what ll be cost of man and materials . Crores are invested in maintaining these machines and training the pilots .
