It is because of maintenance engineers that 44 years old MiG-21 is still flying: Air Chief Marshal
During an event, Air Chief Marshal BS Dhanoa said 'It goes to the credit of our maintenance engineers that today I can fly the MiG-21 MF aircraft which is almost 44 years old. I am sure none of you are driving a car of that vintage.' He also empasized on the need to develop indigenous defense equipment as India can't only rely on imports. We can't wait for indigenous technology to replace obsolete warfighting equipment, he added.
