Squadron Leader Ajit Kumar Choudhury has been serving with Fighter Training Wing since November 1965. As a Flying Instructor, he has flown a total of 2,000 hours. On 16th May 1968, he was authorised to carry out general flying and aerobatics sorties on a Vampire aircraft with a pupil pilot. At the end of the sortie after carrying out a roller take off, he heard a loud thud and noticed the R.P.M. winding down with the complete loss of power in the engine. The aircraft had gained only 300 feet of height and was flying at 170 knots. Squadron Leader Choudhury took immediate action to gain height. With exceptional skill and cool courage, he landed the aircraft safely.
