**The Indian Air Force (IAF) has grounded its entire fleet of Sukhoi fighter jets after one crashed during a routine training exercise in Rajasthan state.**All 100 such planes have been grounded as the IAF carries out “precautionary checks” following the crash.
Two crew members managed to eject from the Russian-designed Sukhoi-30MKI just before the crash on Monday.
Last month Indian President Pratibha Patil rode in a Sukhoi jet, becoming the first Indian woman to do so.
Monday’s crash was the second such incident involving a Sukhoi fighter jet this year.
The air force is believed to have sought assistance from Russia for this investigation, the Times of India reported.
