Squadron Leader Krishna Bihari Singh has been in command of No. 1 (Delhi) Air Squadron NCC since January, 1971. He was selected as the manager/pilot of DG NCC Gliding team for the first National Gliding Championship held at Kanpur in April-May 1973. All competing pilots had to be holders of Gold 'C' Distance Leg Badge which meant performance of a cross country of 300 kilometres. Squadron Leader Krishna Bihari Singh had no experience in glider cross country flying. He took up the challenge to fulfill this condition so that the DG NCC team could participate in the National Championship. He was provided with an Olympia glider which was made airworthy on 20th April, 1973. With barely a week in hand he set about this task in an earnest manner. His attempts at 300 kilometres cross country were unsuccessful on 20th & 21st April due to inclement weather. On the 22nd April, 1973 he was struggling from 1100 hours to gain enough height to set course for Kanpur, a distance of 390 kilometres, but weather conditions were unfavourable. Finally in a daring move he set course from a low height of only 2600 feet and at a very late hour of the day. He was down to a height of 1400 feet over Tilpat Range but managed to continue soaring with skill and determination. After covering a distance of 285 kilometres, he was forced to land short of Kanpur due to poor thermal activity and failing light. He was retrieved to Kanpur the next day by the ground party. After one more unsuccessful attempt, he finally completed a distance of 306 kilometres from Kanpur to Varanasi on the 27th April, 1973 and thus earned a Gold 'C' Distance Badge of the Federation Aironautique Internationale for himself and paved the way for the entry of the DG NCC team into the Championship.
He is the first in the NCC to earn this distinction. During the Championship he was flying an Olympia glider (1947 manufacture) with a glide ratio of 1:18 against modern high performance sailplanes with glide ratios of 1:28 to 1:36. He was competing against veteran glider pilots of the country with far more experienced than him. In spite of these handicaps, he succeeded in securing 4th position amongst 11 participants at the National level.
Squadron Leader Krishna Bihari Singh thus displayed courage, determination, professional skill and devotion to duty in the best traditions of the Air Force.
