William enlisted in the U.S. Army Air Corps on October 29th, 1940. He arrived at Pearl Harbor on December 4th, 1940 and was assigned to Wheeler Field. William was on the Haleina Field, an emergency landing field. "We were on maneuvers testing armament on our aircraft (fighter planes)." When the attack occurred his job was to do armor maintenance of aircraft. Afterwards, he was sent to Hickham field daily to help assemble planes that were shipped in from the states. He also had to stand guard duty at night. "Although I was not assigned to their specific planes our fighter squadron was the only one that was able to get planes in the air. Two of our groups pilots - Taylor and Welsh - got their planes up and shot down several enemy planes. One enemy plane flew over our field, but did no damage that I know of to our equipment." After Pearl Harbor he continued as an aircraft mechanic with duties as helper, crew chief and flight chief and earned the rank of Technical Sergeant. We continued flying practice at Haleiwa, Mokulaiwa, Bellows Field on Oahu, and Barking Sands Field on the island of Kaui.
