Flight Lieutenant Chow Ongpee Maunglang was posted to MiG Operational Flying Training Unit with effect from 09 Sep 91 from a Type 75 Squadron. From his arrival, he applied himself with determination and zeal to promote flying in this unit. Despite his youthful years, he displayed a rare maturity of purpose and design.

On 03 Jun 92, while rejoining after a PI sortie, his canopy exploded in the air. Silvers of perspex cut his face and shattered his cheek-bones, causing excessive bleeding. Despite the pain and shock, the officer retained his presence of mind and initiated an ejection. Though the ejection was successful, the canopy minus the perspex bubble did not separate cleanly. Grievously injured and tumbling down through the air, Flt Lt Maunglang did not panic but decided to fight on. He operated the manual separation lever and decided to eject through the broken canopy perspex. He achieved this and then also opened manual D ring to ensure that his parachute would deploy. Unfortunately, exiting through the canopy, he was hit on the head by the solid frame, causing fatal injuries. The officer fought to the very last breath.

For his acts of courage and exceptional devotion to duty, the President is pleased to award Vayu Seva Medal (Posthumously) to Flt Lt Chow Ongpee Maunglang.
