letter fr 20 Dec. Arepr esen at the NTS. e work week th s se es dr Betts ad ut on a 54 hour om Reeves to e work week. Hereis a 20 Dec. Operations letter from Keith Byrne, Acting Director of the Air Force within AFSWC at this time to ALO which informed them that AFSWC has TF requested 24 B-57 type samplers of Headquarters Air Force and been informed that this requirement cannot be satisfied. I think this letter is documented elsewhere and the Air Force has replied that 15 B-57's, including 4 D's, would be made available. Here is documentation of a communications meeting held in Las Vegas on 20 Dec. 61 and attended by representatives of the 3 labs, Douglas, AFSWC, EG&G, H&N, AEC, and Air Force Organizations with both requir ements and support PR capabilities. A 20Dec. 61 letter from Gen. Booth to the Air Force Chief of Staff discusses the need for samplers for the Task Force. He states, “As you know I am asking for a total of 10, of which only 4 are already modified and 1 of these is in such poor shape as to make its repair uncertain. Because of the time limitations onthe proposed test series I must continue to press for all 10. However, in view of the nature of the proposed series and the over-riding importance of adequate sampling, it would completely unrealistic to undertake the test with less than 5 and even 6 would be the minimum number assigned to positively insure the minimum required of 5 available for any of the 7 larger yield devices programmed. Consequently it is obvious that some D's must be modified by the 15 Mar. deadline necessitated by the proposed schedule of events."
