PRIVACY ACT MATERIAL REMOVED However, the pilots and the two observers were not concerned about their exploits, "We know what we are doing and there is nothing to set excited about "°° Drawing conclusions from its project, the Center's survey group pointed out that thecontamination density readings occurred when instruments and film were placed in direct contact with the contaminated akin of an airplane for extended. periods of time. Airmen servicing an aircraft, however, would probably keep their hands in more or. less constant motion during the operation and would not likely receive as much radiation as was recorded on the meters and film badres. For a person to receive radiation of the same values as those collected during the survey, the project officers reported that an individual would have to come into direct contact with the nose of the airplane or the leading edge of a wing, In addition, the direct contact with the surface would have to be somewhat prolonged, depending upon the intensity of the particles touched to achieve a radiation burn“? The Uirh Altitude Nuclear Shot “hen the high altitude explosion was detonated on the morning of 6 April 1955, it represented the culmination of about 18 months of intensive preparation at the Air Ferce Special “leapons Jenter. ‘Early in October 1953, the Armed Forces Special ‘leapons Prosect was interested in a nuclear warhead for antiaircraft rockets. 130 AFWL/HO That agency, therefore, SWTH-2-003h un
