Squadron Leader Natarajan worked tirelessly and it was by his singular determination and dauntless efforts that relief was provided in the shortest possible time to the affected area.

Squadron Leader Natarajan has over 5000 hours of helicopter flying to his credit, out of which 3000 hours have been flown as Captain over hazardous mountainous terrain in the East and in offshore flying over unforgiving seas of West and East Coast. Under his direct supervision as Flight Commander the unit flew a total of over 3000 hours, accident free, in the first year after induction. This was possible only because of Squadron Leader Natarajan's untiring efforts, zeal, devotion to duty, exemplary leadership and understanding of the critical problems in their totality.

For displaying exceptional professional skill, effective managerial ability and undaunted devotion to duty, the President is pleased to award VAYU SENA MEDAL to Squadron Leader Viswanathan Natarajan.

Wing Commander Viswanathan Natarajan was one of the four Mi-8 pilots in the IAF contingent of the IIIrd Indian Arctic Expeditions. On the 28th December, 1983, he was assigned to transfer heavy construction and other material from the ship to the base camp. The terrain was unknown and forbidding. The unpredictable adverse weather with extremely strong surface winds and persistent low visibility, made the helicopter operation extremely difficult. All these hazards and the non-availability of other helicopters did not deter Wing Commander Natarajan. He met all the flying commitments by flying 61:30 hours in 212 sorties. It was due to his persistent efforts that the availability of heavy construction material was ensured and the Army engineers were able to complete the construction of protp station in time.

Wing Commander Viswanathan Natarajan displayed indomitable courage, determination and devotion to duty of a high order.
