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.
