Complete still coverage was also obtained, including photographs that can be used for historical purposes by the various Task Units and Task Groups. All film exposed on Operation Ivy, both still and motion picture, will be catalogued and indexed. The cataloguing of the motion-picture film will be accomplished utilizing the microfilm process, with one copy of the final catalogue distributed to AEC, Los Alamos, and one copy to AFSWP Headquarters, Wash- ington. AFSWP is to be the coordinating authority for additional prints required by DOD agencies of anv stock footage shown in the catalogue. No restrictions have been imposed on the length of the documentaryfilm; however, approximately 45 min running time is desirable. The film is to document Operation Ivy, the problems encountered, and the solutions to these problems. Oneof the first steps in the production of such a motion picture was to prepare a firstdraft motion-picture script. This was accomplished by TU 9, and this draft script was submitted for approval to CJTF 132. In the Forward Area, TU 9 completed the photographic program in accordance with these approved plans, Owing to the nature of Operation Ivy, it was necessary that each ground photographic crew be completely mobile and all necessary camera and allied equipment be made a part of that crew. A total of four ground crews, which included one synchronous sound crew, were utilized at Eniwetok Atoli and Kwajalein Atoll for Operation Ivy. Three C-54 aircraft were obtained on loan from MATS. The modifications for these aircraft were fabricated at Wright-Patterson Air Force Base and Lookout Mountain Laboratory, and most of the modification work was performed at Hickam Air Force Base. All three C-54 aircraft participated in three practice missions prior to Mike Day, and all three aircraft were flown on the actual mission. Two practice missions were flown prior to King Day, and all t three aircraft were flown on King Day. Remote camera installations utilized on Operation Ivy were designed and constructed by Lookout Mountain Laboratory and were located at the following stations during the operational phase: 1, Station 390.01 (Engebi): One 16-mm camera was pointed at the north and west sides of the multistory building on Engebi. This camera was triggered by photocell and was loaded with a special panchromatic film, emulsion type 918. The camera operated successfully on both Mike and King Shots. 2. Station $90.02 (Engebi): One 16-mm camera was pointed at the south and west sides of the multistory building on Engebi. This camera was triggered by photocell and was loaded with a special panchromatic film, emulsion type 918. The camera operated successfully on Mike Shot, but on King Shot it was turned to cover the blast and did not operate. 8. Station $90.03 (Runit): One 16-mm camera was pointed at the dock on Runit and also covered the burst. This camera was triggered by photocell and was loaded with a special panchromatic film, emulsion type 918. The camera operated succesafully on Mike Shot, but this camera station was removed for King Shot. 4. Station 390.04 Qaptan): One 16-mm camera pointed at the burst, shooting through the trees on Japtan. This camera was triggered by photocell and was loaded with Eastman color negative. The camera failed to operate on both Mike and King Shots. 5. Station $90.05 (Eniwetok): One type K-25 aircraft camera was pointed at the burst from the north tip of Eniwetok. This camera was triggered by photocell and was loaded with Ektachrome film. The camera failed to operate on Mike Shot, and this installation was removed for King Shot. 6. Station $90.06 (Eniwetok): One 16-mm camera was pointed at the beach club and at the burst. It was triggerea py photocell and was ioaded with Eastman color negative. This camera did not operate on Mike Shot and was removed for King Shot. As of 25 November 1952, the following amounts of film, both still and motion picture, had been exposed during Operation Ivy: 38
