Wing Commander Sasidharan Nair (3669) Accounts joined the Indian Air Force as an airman on 3rd March 1945 and was commissioned as an officer on 28th August, 1949.

After early years of service as an Accounts Officer at various Stations and Wings, he became the Senior Instructor in Accounts at the Air Force Administrative College, where he was responsible for the training of new Accounts Officers for the Air Force. Thereafter, he served as the Deputy to the Command Accounts Officer at a Command Headquarters and as the Commands Accounts Officer of another Command. For his good work, he was commended by the Chief of the Air Staff in 1966.

In Wing Commander Nair's present appointments at an Air Command, there was a large number of stores transactions awaiting finalization. This backlog had accumulated in the wake of the Chinese aggression in 1962 and the Indo-Pakistan hostilities in 1965, because the units concerned had changed from peace-time accounting procedures to operational procedures and finally reverted to peace time procedures after the two conflicts. Using bold and unconventional methods, he was responsible for clearing 2400 out of 2500 cases in a period of 18 months. He has also initiated a system in the Command, whereby Station Commanders can easily watch the trend of expenditure under locally controlled heads, thereby reducing wasteful expenditure.
