Task Force SEVEN was under the direct supervision of Brigadier General (then Colonel) Faul T. Cullen. In order to insure adequate and accurate photographic coverare of Task Group 7.6 activities a liaison officer, Major G. Ky McDonnel, was designited on 27 February 1946 to assist in documenting the task group activities, Attempts to establish liaison before debarkation from Terminal Island were unsuccessful since General Cullen was in Washington, D.C, However, a telephone conversation with Major Robert T. Elliot, of General Cullen‘s staff, did establish the fact that a photographic crew would be assigned to cover Task Group 7.6 activities throushout the operation and that this crew would be billeted aboard the USS BAIROKO, Major Ellot also stated that he would provide photographic equipment aboard the BAIROKO between Terminal Island and Pearl Harbor. A conference with Herbert I, hiller of Los Alamos Scientific Laboratory, the desumentary and classification officer of Joint Task Force SEVEN, revealed that the Atomic Energy Commission desired accurate and complete coverage of all TG-7.6 activities. Sufficient movie film and film packs would be available to complete the mission and provide for a two hour rt we. ¢ yr documentary film. It was also established that the Armed Forces Special veapons Project would have the film available for use in a training film providing AHA security regulations were not breached. It was also determined that there would be a "still" photographer aboard ths BAIROKO while enroute to Pearl Harbor and that this photographer had a "Q" clearance pending. This automatically limited the amount of information which he could document by photography. Material Covered by Photography. This photographic crew covered all radiological safety activities of JTF--7 with additional coverage of the technical measurements section of TU-7.606- In general the mterial covered can be grouped into the following: 1, 2.
