The services of Wing Commander Subramanyan Chenna Keshu were loaned from the I.A.F. to H.A.L in May, 1960, as Prototype Production Engineer. When the programme for building H.F.-24 prototype production began, this officer was given the task to study the best method of production based on an examination of the drawings of this indigenous supersonic fighter. He was also to study the latest method of manufacture and to produce the parts in the shortest possible time. This officer contributed in a significant manner to the flying of the first Prototype in June 1961 and brought to bear on his task technical and organizational ability of a high order. In addition, in the past 2 Ã‚Â½ years of his service with the H.A.L., the officer has built up a team of engineers and technicians, which is now engaged in the preparation of quantity production of H.F.-24.
