The family, which resides in Garnala village near Ambala city, is yet to receive the body for the last rites.
According to official information, the martyr's body would be airlifted to Ambala airbase late Sunday night.
Gursewak had joined Indian Air Force about six years ago after completing his graduation. He had got married just 45 days ago.
His father, Sucha Singh, a farmer, said that he received information about Gursewak's martyrdom from his elder son who is an officer in the army and asserted that he was proud that his son had laid down his life for the country.
Gursewak, described as an intelligent and bright youth by his father, had cleared the Air Force exam in the first attempt.
"Legendary freedom fighter Bhagat Singh was his icon," Sucha said.
Haryana's Heath Minister Anil Vij visited Gursewak's residence on Sunday afternoon to console the family.
Meanwhile, Deputy Commissioner Ashok Sangwan said that the body of the martyr would be cremated with full state honours.
