I BUSTER CHARLIE. The third event occurred on 30 October 1951, when a Kirtland plane dropped another device over the Nevada Test Site. B-29 aircraft and two T-33 aircraft collected samples, Two The third B-29 sampler collected samples from the cloud five hours after detonation, Control of the T-33 samplers was still unsatisfactory, The aircraft controllers set-up a grid map so the B-29 samplers could give more accurate cloud positions. Control was further complicated, however, by not having electroni:s equipment at the control point, and Colonel Fackler observed the sampler aircraft through field glasses. At this point, it was decided the radiological officers should have more control over the aircraft as another possible solution.” ” BUSTER DOG. The DOG Shot was dropped on 1 November 1951. The cloud retained its "puff" configuration for a long time and four samplers had little trouble with their missions.>- BUSTER EASY, A Kirtland aircraft dropped EASY on 6 November 1951, and the largest array of the operation gathered data from the shot. Both B-29 samplers suffered difficulties, The first had engine trouble and was unable to climb above 31,000 feet and returned with a poor sample, The second B-29 aircraft made one pass through the cloud and the radioldgical officer reported the crew had been exposed to an extremely high radiation dosage, After he repeated the reading with the same results, the radiological officer at the control point ordered the aircraft to return to base immediately, Ls AFWI{HO On the ground, it was discovered SWEH~2 -003), uu
