NEW DELHI, May 24 (Xinhua) -- Indian military Wednesday intensified search operations to trace missing Sukhoi-30 MKI fighter jet with two pilots on board.

As the search enters second day on Wednesday, rescuers have not been able to find out the missing jet so far.

The fighter jet belonging to Indian airforce went missing Tuesday after taking off from the Tezpur Indian airforce base in northeastern state of Assam.

According to officials, the fighter jet was on a routine training sortie and lost radio contact with the airbase.

"A massive search operation has been launched to trace the fighter jet and missing pilots," a defense spokesman said. "Help from civil administration has also been sought for the search and rescue effort."

Meanwhile, a local news agency reported that rescue mission for the missing Sukhoi-30 aircraft has been halted for bad weather conditions in the area.

The Sukhoi-30 is a Russian-made twin-engine supersonic fighter jet.

In March this year, a Sukhoi crashed in Rajasthan's Barmer. Since the induction of Sukhoi-30 fighter planes into Indian airforce in 1997, seven have crashed.
