Station 65 - Piiraai, Bokonaarappu, and Teiteiripucchi ~ EG&G. was a 14 foot by 14 foot storage tent without a floor slab. were required. This No drawings Station 66 - Piiraai, Bokonaarappu, and Teiteiripuccht - EG&G. On those islands that were too small to justify a runway for airplanes, an asphalt mat 150 feet square was laid to provide a landing area for helicopters., Station 69 - Runit, The Aomon Group, and Engebi - EG&G, Based upon discussions with J-Division, H & N submitted sketches of these stations on October 19, 1949. Los Alamos then made preliminary sketches for the timing and communications stations, which were received by H & N on Novem ber 18, 1949. The building had 3 interior sections with but one doorway into the building. The three sections were all & feet high inside, and the other side dimensions were 5 feet, 6 inches by 15 feet; 8 feet, 10 inches by 7 feet, 6 inches; and 8 feet, 10 inches by 7 feet. Originally all walls and roofs were 12 inch reinforced concrete sections. Because of revised pressure data for Runit, the walls and roof were changed to 15 inch sections. The drawings were completed February 8, 1950 and ap- proved for construction on March 24, 1950. Stations 70a through w - Engebi, and Stations 70a through z - The Aomon Group - Bio-Med. These stations were the animal cylinders, which were furnished by the Bio-Med group. The 8 foot by 10 foot by 1 foot concrete bases were designed and constructed by H& N. The size and location of these bases were obtained from a conference with the J-Division repre- sentative in the H & N offices on June 27, 1950. Stations 7la through d - Engebi, and Stations 71% through g - The Aomon Group - Bio-Med, Same as Station 70. Station 71d on Engebi had to be relocated on October 23, 1950 and Station 71g on October 31, 1950 because of a lack of area. Stations 72a through i — Engebi - Bio-Med. Except for Station 721, these statione were the same as Station 70. The bases, however, supported longer cylinders. Base dimensions were 10 feet by 12 feet by 1 foot. Each station consisted of 9 slabs. Stations 72a, h, and g were relocated on October 24, 1950; Station 72h was deleted from the program on October 26, 1950. On January 5, 1951, a letter from Los Alamos authorized H & N to add Station 724. Station 724 was to have been three 21 feet by 10 feet rafts to hold three long cylinders. On January 17, 1951, drawings were issued to the field. The floats were to be standard Navy design, but because it was found that additional buoyancy would be needed H & N had to alter the Navy design. In February 1951, a jetty was constructed to pro- vide a quiet water area for small boats. This jetty was on an extension to the Bio-Med program line; therefore approval was given to utilize the outboard end of the jetty to locate Station 721 on firm ground. Because of this, Station 721 was changed to 8 large cylinders and 1 small cylinder on February 28, 1951. 5-167
