A large hump-backed steel hangar, the "Butler Hangar", 160 feet X 130 feet, transported from Trinidad (probably from the former Waller Air Force Base, closed 28 May 1949 due to budget cuts), was erected at Auxiliary Field 3 between 1 April and ~10 July 1950, by personnel of Company 'C', 806th Aviation Engineering Battalion, under Captain Samuel M. Cable, and the men of the 550th Guided Missiles Wing.
