On the south side of the runway was the steel-framed L-13 maintenance building with aluminum siding and roofing, very similar to a standard "Butler" building of 50-foot clear width. The nearby Air Task Group Headquarters Building and the base operations building were standard aluminum structures. To one side of the latter building was built the three-story control tower. The first two stories were designed for wood frame construction with aluminum siding. The control room was designed to project out from its two-story base and to be enclosed with continuous aluminum sash set at an angle to reduce glare. To receive the sash and to support the roof, aluminum I-colums were used. A catwalk was designed to surround the control room, and access was planned by means of an exterior wood stairs. The majority of the remaining structures on Eniwetok Island were designed as standard aluminum buildings except those so small that the standard building could not beeconomically used. These were wood frame with aluminum siding. . Buildings of this type included the inflation shelter, weather station, sentry post, and others. Two open-air theatres were designed; one with a seating capacity of 712; the other, with a capacity of 818. Seating arrangements in both were wooden benches on fill sloping down toward the screen. The seating arrangement, viewing and projection angles, and the projection room design were based on the same criteria as for theatre on Parry and resulted in similar layouts. However, no shelter was provided over the rear seats as at Parry. Instead, the projection rooms were designed as the second floors of small two-story buildings of wood frame construction with wood sheathing and aluminum siding and roofing. The lower floor of the building was designed for use as a recording room and as a radio station at the Air Force theatre, and as a recording room at the Army theatre. The Air Force theatre had a stage to accommodate local talent or USO shows; the Army theatre had a speaker's platform at the right of the screen. Beer halls and beach clubs were provided to be constructed by the Army task group personnel of available materials, RUNIT ISLAND AND THE AOMON-BIIJIRI-ROJOA GROUP All structures on the experiment islands were to be used for a shorter period of time than those on either Eniwetok or Parry. They were not expendable and dismantling before shots was specified. Therefore, to minimize dismantling effort all personnel were quartered in tents. A recreation or refreshment tent was provided at each site. However, because tents were thought to be inadequate to house most of the other camp facilites, aluminum structures were used. The only exception, in each case, was the reinforced concrete, blast-proof power plant which was required to supply power for a short time after the experiment. Showers, latrines, and timber grease racks were designed as for Parry and Eniwetok. 5-117
