Group Captain Varun Singh won the Shaurya Chakra in August.
Group Captain Varun Singh, the only survivor of the helicopter crash in which Chief of Defence Staff General Bipin Rawat and 12 others were killed, is "critical, but stable". Defence Minister Rajnath Singh told parliament that he is on life support and "all efforts are being made to save him".
Group Captain Singh is being treated for severe burn injuries at the military hospital in Wellington. He is now being flown to a hospital in Bengaluru, defence authorities in Nilgiris told NDTV.
"He is being shifted to Bengaluru. I have reached Wellington," his father Col Singh was quoted as saying by news agency PTI.
On his son's condition, he said: "I can't say anything about that... I am not sure."
"He is critical but stable at the moment," said officials.
Col KP Singh and his wife Uma were in Mumbai at the home of their younger son Tanuj, a Lt Commander in the Navy, when they received the news.
Col Singh's neighbour Lt Colonel Ishan R (retired) told PTI: "I spoke to Colonel K P Singh this morning. He said his son was a fighter and will come out victorious."
The Air Force officer won the Shaurya Chakra in August for his courage in handling his aircraft after it was hit by major technical issues during a sortie last year. He managed to land his Tejas fighter safely.
Group Captain Singh had gone to Sulur to receive General Rawat and escort him to the Defence Services Staff College, Wellington. General Rawat was to address the faculty and students at the institute, where Group Captain Singh was Directing Staff.
Bodies recovered from the crash site were badly charred, said rescue officials.
