II The Air Force Special Weapons Center launched a bomb-carrying bombardment aircraft from Kirtland to drop the first shot, ABLE, of TUMBLER/SNAPPER on the morning of 1 April 1952. went off without a hitch, The sampling missions The B-29 controller called up the B-29 sampler, then the four T-33 samplers and each made several passes into the cloud. After their removal by radiological crews, the samples were pot into a courier aircraft operated by the 90lst Support Wing (Atomic) and flown back to Kirtland for transfer from there to the Los Alamos Scientific Laboratory.°? The BAXER Shot occurred of 15 April 1952. This time the B-29 control aircraft penetrated the cloud because the regular B-29 sampler had returned to base. The cloud scattered in several directions, but good samples were obtained by the control and four T-33 aircraft,° CHARLIE Shot was dropped on 22 April 1952, and sampling progressed as scheduled, One of the T-33 samplers aborted while another T-33 sampler returned to Indian Springs where the papers were removed, new sampling paper installed in the filter tanks, with a new crew it sampled the cloud the second time. During this shot the first of the missions occurred with the Strategic Air Command F-8)G pilots, After the T-33 Samplers performed their missions, the control aircraft called five F-8),G airplanés, one-by-one, up to the cloud for sampling runs on The last airdropped device, DOG, was detonated on 1 May 1952, Except for some mechanical difficulties encountered by the B~29 sampler, _ the T-33 and F-8)G aircraft operated very well, Su ArenJWo 62 SWEH-2-003) q3 “Wan
