xT that an aircraft better than the F-8),G be modified for collection of samples from within the cloud resulting from each of their nuclear test explosions, By better, they mean primarily the capability of obtaining samples at higher altitudes than is feasible with the F-81G,"! From their studies, key men from Air Force Special Weapons Center decided that the B-57 was the outstanding airplane to be used in sampling operations and had set out to get them.” leaders that the need was genuine But, persuading the Air Force was an all-agencies task, Dr, Norris E. Bradbury and Dr, Alvin C. Graves of Los Alamos Scientific Laboratory sent strong letters listing their requirements for futute tests and mentioned the unsatisfactory samples obtained during previous tests.” On 6 June 1955, Dr. William Ogle, Los Alamos Scientific Laboratory, foresaw unsatisfactoryresults during REDWING following announcement that the number of B-57 aircraft to be made available was being reduced. *, . . reduction in number of B-57 type aircraft for REDWING sampling is unsatisfactory to this headquarters," he messaged, ", . . It is difficult to understand why USAF is not prepared to supply at this date number and type of aircraft considered by these responsible Air Force agencies as required to satisfy our mission requirements on minimm basis, particularlysurprising. - e® Reduction And to insure that possible abetting agencies knew of the reduction, he sent information copies to them. /° Admitting that little was yet known about the radioactive cloud, Dr. Duane C, Sewell of the University of California Radiation Laboratory, wrote to Brigadier General Howell M, Estes, Jr., on 17 May 1954, ". 2. 243 SWEH -2-003h 1 Q- AFWL/HO o° Ua yw
