-2- a LASL memorandum $J3-G0-312, dated 21 January 59. En the discussion about the use of missles for nuclear detonations, a LASL 3 memorandum #J3-W-82, dated 29 June 59, subject “High Altitude Nuclear Detonations wa Johnstong Island," is referenced for further information. In discussing the details of the open sea method od testing, six different sters are referenced as having covered various aspects of this subject beginning April of 1959 and going through a J-3 report on 19 August 59, #J3-W-96, subject esting of Nuclear Detonations on the Open Sea." All of these should be ih the Jivision files and perhaps the J-3 files (whereevr “hey are). They are Listed Page 76 of this report. The discussion of underground testing notes the accomplishments to date, and ates that there are presently five five-hundred foot vertical holes available in 2a 3, and four twelve-hundred foot holes in the planning pk phase, with three- re old holes which may be re-usable if cleaned out. AJ -6 memorandum #J6-8241, ved 2 July 59, addresses the feasibility of vertical hole tests. 7 Alb August reply from Fleming to Colonel Thomp son gives his personal opinion erm = aat there will be no nuclear tests requiring sampli ng other than the Rover and XCART (PLOWSHARE) type for a long time to come. Thus, based on his opinion that-— andia will have completed development of a drone aircraft sampling system by ne id of the calander year 29, he is saying that Livermore will not need the hoe6-A “ter OXCART if his assumptions prove to be true. His estimate of a date for (CART, nuclear testing which depends on the politi cal situation and specifically fA's authorization which has not been forthcoming, can not be done prior to the wiraing of 1960. 4 3 é -
