om A December TWX from Ogle to Task Force Personnel notes that there will bea u 28 December meeting in Las Vegas to discuss J-3 type operations plans for Hilo. wee A 20December letter from Col. Joseph Byrne of AFSWC to the manager of ALOO, outlines the status of the procurement of sampler aircraft todate and in ‘particular provides this for LASL since they are spending time and money procurring particulate sampling tanks to equip the fleet and therefore must Know what size the fleet will be. CL The original AEC request for 24 sampler configured B57 Aircraft cannot be satisfied; the USAF response initially has been that four B57D's and 1! B57B/C/E's as well as 15 B57's will be made available. Subsequent guidance which includes planning for a maximum of only one event per day B57D's and has led to a new determination of requirements for only {0 12 B57B/C/E's. AFSWC has sent this restated and new requirements on to higher headquarters requesting reconsideration of Air Force support. ; John Foster on 2] December in a TWX to Betts put his support behind the LASL proposed very high altitude event. standing Island He stated that Livermores present under- is that there is only 2 high altitude shots planned from JOhnston and that LRL will piggyback on these shots to develop space tasting techniques. Of these shots, one is toolow an altitude (50 kilometers) but the other one (at 400 kilometers), Livermore hopes to use to test their diagnostic methods. Livermore feels that a second! shot sbove 400 kilometers would be desirable and therefore recommends the retention of the DOD/LASL proposed 1000 kilometer, 165 KT test. A 20 Dec. TWX from the Chief of DASA to DMA and AFSWC requests AFSWC to proceed with the design and procurement of sea borne targets for the airdrops including radar reflectors, radar responders and lighting and requests the AEC to provide necessary initial funds. 4 ‘ A 20 Dec.
