Two pilots and two border security force (BSF) personnel were killed on Friday when a Chetak helicopter crashed in the hilly terrain of Rajasthan's Sirohi district.
The incident took place at Bahadarpura village, around 60km from Mount Abu, at 4pm when the helicopter was flying from Gandhinagar in Gujarat to the air force base at Jodhpur.
The mishap occurred just two weeks after a Pawan Hans helicopter had crashed in Arunachal Pradesh on April 30 killing chief minister Dorjee Khandu along with four others. The wreckage was found on May 4.
"The helicopter went to Gandhinagar in the morning and took off from there for Jodhpur around 2.20pm. It was scheduled to reach Jodhpur at 4.20pm. However, the chopper lost contact with the air traffic control and was not traceable on the radar," said RC Dhyani, deputy inspector general of police, BSF.
Those killed include Captain BPJS Bal, a pilot employed with Pawan Hans Helicopter Limited but on deputation with BSF, co-pilot Vivek Chaudhary of BSF, technician-cum-engineer SS Chopra, and BSF sub-inspector Sohan Lal.
Senior officials including Sirohi additional superintendent of police Ram Gopal Bishnoi, additional district magistrate Mahipal Singh Ujjawal, and officials of the BSF rushed to the spot on hearing about the crash.
Ujjawal said the bodies were charred beyond recognition.
Prima facie, the helicopter is suspected to have crashed into a hill but the exact cause can be ascertained only after technical examination of the spot and helicopter parts, officials said.
