The normal commercial air routes across the Pacific run along the Honolulu-Wake-Guam route to Japan and the Honolulu-Samoa-Fiji Island routes to Australia and New Zealand. The former route might have been utilized to Eniwetok by the inclusion of a 600 mile connecting service between Wake and Eniwetok. However, this would have constituted an expensive operation and would have entailed the establishment of air-sea rescue services and the establishment of a Holmes & Narver traffic agent at Wake Island. In comparison with other off-continent locations in which con- struction projects are in progress, Eniwetok is unique insofar as the feature of its location is concerned. Such locations as Alaska, the Philippines, Arabia, Guam, North Africa, and Iceland are all on direct steamship routes, on regularly scheduled air routes, or on both. Availability of commercial cargo ships and commercial aircraft was investigated. These were found available for charter and could have been utilized either as regular means of transportation or as temporary means of meeting emergency situations. During the later phases of the program, one shipping firm offered to discharge minimum shipments of 500 tons at Eniwetok at commercial rates. DISTANCE FROM 0 L Eniwetok Atoll is approximately five thousand nautical miles from the United States ami approximately twenty-five hundred nautical miles from the Hawaiian Islanis. It was found desirable to recruit about onethird of H & N personnel from the Hawaiian Islands, with the remainder coming from all parts of the continental United States. Certain emer- gency purchases of supplies were made in Honolulu, but the most of the supplies came from the continental United States. Military shipments usually sailed westward from San Francisco in a wide circuit of the Pacific, calling in sequence at Honolulu, Kwajalein, Guam, and sometimes Okinawa and Japan. Although this was obviously efficient from the standpoint of military servicing of a number of peacetime installations, from the standpoirt of this Project, the route produced an indirect and interrupted schedule. It resulted in extending the time required for the voyage from San Francisco to Eniwetok to a period of fifteen days and upward, and served to increase the time interval between initiation of procurement on any item and its availability for use at the Jobsite. Air shipment via the MATS system was, of course, much more rapid, but the volume of cargo utilized on this Project was such that only a minute fraction could be handled as air cargo. The average interval of time from departure of cargo from San Francisco via MATS until its ar- rival at Eniwetok was approximately four days, much of which time was consumed in unloading and reloading in Honolulu. MATS service was, however, invaluable for the transportation of critical items which were in urgent demand from time to time.
