Sgt Yoganandam Kalluri is on the posted strength of one of the Air Force Helicopter Units since 13 Jan 90.

On 03 Jul 90, a helicopter had to be left behind at Amar due to engine flame out on ground. The retrieval of the helicopter was planned after an engine change. Amar helipad is at a height of 19000' AMSL and on the Actual Line of Control, within range of enemy artillery fire. The post is constantly shelled by the enemy.

The engine was flown to Amar on 12 Jul 90. During this period the post was under enemy shelling, when Sgt Yoganandam under instruction of Flt Lt Sreepal, Officer incharge of the team, assisted the offloading of the engine. The task of engine change could commence only in the evening due to enemy shelling. Sgt Yoganandam with the help of other technicians carried out the engine change during the night with the help of kerosene lamps and torches. Finally the helicopter was flown out at 1740 hours on 13 Jul 90.

For his exceptional devotion to duty, selfless service and thorough professionalism, the President is pleased to award Vayu Seva Medal to Sgt Yoganandam Kalluri.
