Early in 1957, the basic concepts and general plans of evacuatior. 2. Later, 28 projects began to submit their monthly status reports, were determined. Based upon this, requirements for ships, boats, and aircraft were determined and requested of JTSEVEN. more detailed information was compiled in the J-3 Section of the Task Group. This waspublished early in February 1958 in an abbreviated form in the two atoll event booklets as appendixes to the Task Group Operation Plan 1-58. 3. , Final detailed planning took place at the Proving Grounds when each task unit, one to two w-eks before each shot, sutmitted its project's evacuation and re-entry cards to the J-3's on Bikini and Eni- wetok Atolls. With this latest data, a detailed check list, arranged chronologically, was prepared for each shot and given wide distribution to other task groups so that adequate support could be scheduled.
