India's first military chief General Bipin Rawat, his wife and 11 other armed forces personnel were killed in a chopper crash in the southern state of Tamil Nadu on Wednesday. The 63-year-old decorated Chief of Defence Staff (CDS) was on his way to deliver a lecture at the Defence Services Staff College in Wellington when the ill-fated Mi-17 V5 helicopter crashed just before landing around 11.45am in the hilly terrain of the Nilgiris in the state's Coonoor district and burst into flames. A senior Air Force officer accompanying the four-star General survived the fatal crash but sustained severe burn injuries. He has been identified as Group Capt Varun Singh, who is currently under treatment at the Military Hospital in Wellington. Read: India's military chief feared dead in chopper crash
