A short history on Military.com unit page:
Apr 02 803rd Engineer Aviation Battalion WW11
When the Japanese attacked the Philippines on Dec. 8, the 803rd Engineer Battalion was stationed at Fort Stotsenburg, next to Clark Air Field, 50 miles northwest of Manila on the island of Luzon. The 803rd extended runways and built landing strips at Clark and nearby facilities. Company B was constructing an entire new airbase for fighter planes at Del Carmen, south of Fort Stotsenburg.Word of the Pearl Harbor attack reached Fort Stotensburg early on the morning of Dec. 8 (Dec. 7 in Honolulu). Despite this advance warning, all but two of Clark Field's aircraft were on the ground when the Japanese struck. At 12:15 p.m., Japanese bombers attacked Clark and Fort Stotensburg, followed by Zeros strafing B-17s and P-40s loaded with fuel. The Japanese planes also attacked soldiers' barracks, aircraft hangars and warehouses. Air crews and other ground personnel attempted to fight back and evaded strafing Zeros to help wounded comrades. Simultaneous attacks at Clark Field and Iba Field destroyed American fighter planes and heavy bombers, and within a few days, the Japanese had neutralized American airpower in the Southwest Pacific
