and the 38th Reconnaissance Squadron were assigned to the 19th Bombardment Group. The 3rd Air Base Squadron, also assigned to the 19th Bombardment Group, was the first to arrive on base. Headquarters, materiel, quartermaster, ordnance, and signal detachments accompanied it. On 10th April, the squadrons began operations. Because B-17s were in short supply, the pilots trained on Douglas B-18 Bolos and Northrop A-17s, as well as Stearman PT-17 biplanes. Under the command of Lt. Colonel Eugene Eubank, the 19th Bombardment Group focused on precision, high-altitude, and formation flying. They also flew mock attacks on New Mexico villages and ranches. Eubank was known for being a taskmaster, demanding that his pilots gain extensive cockpit experience and that the men cross-train as navigators and bombardiers. As such, it was purported that every B-17 flight had a half-dozen pilots aboard, two flying, two practicing dead reckoning and celestial navigation, and two making practice bomb runs. Ferrying command training The 19th Bombardment Group transferred to active duty in September 1941. It was replaced by the AAC Ferrying Command Specialized Four Engine school. The school operated under the Army Air Corps Ferrying Command, which had been established in late May 1941 and charged with transporting aircraft overseas for delivery to the Royal Air Force. The students were training to ferry Consolidated B-24 Liberator bombers, (the aircraft used at the Four-Engine School) and other multi-engine aircraft to the RAF in Great Britain. TWA chose Albuquerque for the school's location because of its 10,000-foot runway, which could accommodate B-24s, as well as its fair weather. The students were trained in pilot skills, instrument flying, meteorology, radio, briefing, and general transition. TWA pilots and ground crews were readily available as instructors; the difficulty was in housing the students because base quarters were not finished. Consequently, they doubled up in the barracks. The first contingent of B-24 trainees arrived in Albuquerque on 19 June 1941. The facility was officially titled the Air Corps Ferrying Command Four-Engine Transition School but was unofficially referred to as the "Four-Engine School" or "Jack Frye School"—for the president of TWA. Its location on the base was called the Eagle Nest Flight Center. Using Link Trainers and B-24 training aircraft, the TWA instructors trained more than 1,100 pilots and crewmen during the eight months the company operated the school. On 7 February 1942, the U.S. Army transferred the training function from TWA back to the
