Harry R. Thomas was born on July 10, 1911, in Philadelphia, Philadelphia County, Pennsylvania. He enlisted in the service on March 15, 1943. He served in the 787th Bomber Squadron, 466th Bomber Group, Heavy, as a Sergeant and Top Turret Gunner on the B-24 #42-95084 “Bird Dog” during World War II.

On the morning of July 13, 1944, a B-24H Liberator nicknamed Bird Dog departed RAF Attlebridge in Norfolk, England, on a combat mission targeting Saarbrücken, Germany. Commanded by Second Lieutenant Adam E. Wunderlich, the bomber was carrying twelve 500-pound bombs intended for the assigned target. Shortly after takeoff, the aircraft encountered difficulties while climbing away from the airfield under unfavorable weather conditions. Historical accounts indicate that the area was affected by mist, extensive cloud cover at approximately 3,000 feet, and visibility reportedly reduced to less than one mile. During its initial climb, the Liberator apparently experienced engine trouble, and an eyewitness reported seeing one of its wings engulfed in flames as the aircraft descended toward the marshland near Low Farm in Tunstall, within the parish of Halvergate, Norfolk. Unable to maintain controlled flight, Bird Dog crashed into the marshy terrain before reaching its intended target. The impact completely destroyed the bomber and resulted in the deaths of its crew members. Although investigators considered the possibility of an engine fire or a loss of control during instrument flying, the exact cause of the accident could not be conclusively determined. Despite the severity of the crash, the aircraft's entire bomb load of twelve 500-pound bombs remained unexploded upon impact, leaving a significant hazard at the wreckage site.

Sgt Thomas is now buried in the Cambridge American Cemetery and Memorial, Coton, South Cambridgeshire District, Cambridgeshire, England.
