S. Air Force L-5's, L-13's, and H-5 or H-15 helicopters and was used for transportation of personnel, mail, and small packages, The L-5 has a capacity of pilot, one passenger, and twen- ty-five pounds of cargo; the L-13, pilot, three passengers, and one mmndred pounds of cargo; the H-5 or H-15 helicopter, pilot, three passengers, and seventy-five pounds of cargo, During the construction phase of the Project, it was necessary to use only three or four Model L-5's at any one time. However, after ar- rival of the scientific and military personnel, and immediately ing and following each "shot," as many as thirteen L-13's, preced- five L-5!'s, and four H-5's or H-15's were required simultaneously during the course of a day's operations. All aircraft were based on Eniwetok Island. However, each morning at approximately 7:45-a.m., the required number of aircraft for the day's operation would arrive at Parry Island, from which point all dispatching was done. The number of aircraft required was determined by the dispatcher at Parry and reported the previous evening to the operations officer of the Liaison Unit at Eniwetok. This number was based on the advance reservations already booked, together with a general estimate of the re- quirements for the following day. As a rule, the requirements were met as requested; however, because of maintenance and overhaul schedules, it was sometimes necessary to reduce the number of planes, and this reduction resulted in considerably tighter schedules if standby planes were not available. The five main airfields were located on Eniwetok, Parry, Runit, Biijiri, and Engebi, with emergency auxiliary strips on two other small islands, Dispatching the l-passenger L-5's was relatively simple, but 16-7
