February 1950: Pf =<... ~~ te Both J-Division and P-Division report on their accormmlishments and status of the development of the packages for the Villa Sierre and Villa Yotel vrorrams respectively. P-Division reports on the second of a series of four flights of their instrumentation aboard Atlas Launcheé from Cape Caneverial on 11 Feb. 1960. This particular flight carried in the pods ea two-crystal proton telescove and @ gamma-ray Phoswich" counter. The data received was recorded 2t ground stations at Canaveral, intigua, and Ascencion Island and looks satisfactory. Also, data reduction is proceeding on the counting rate versus altitude data from the three neutron counter flights from Tonopah. The next program letter from Teller to Shute on 2 Feb. 1960 opens with some a Gu~ discussion of the main problem which is the lack of testing: no nuclear tests have now taken place for almost a year and a half. Any estimate of the probability of their resumption either this year or next involves considerable uncertai nty. Therefore, the lab must make plans to cover the situation both in case of a resumption
