IT Evaluating Jet Samplers The Be29 bomber had a number of disadvantages as samplers, First, the big aircraft required a larger crew, which resulted in a larger number of people exposed to radiation during a mission, The T-33 jet aircraft, on the other hand, exposed only two individuals, Farthermore, the B-29 bomber was slow, subject to extended radiation while it went through the cloud. The T-33 jet was much faster, performing its mission more efficiently. The T-33 being a smaller aircraft, gathered radiological contaminations over a smaller area of surface than the B-29, Finally, the jet aircraft returned to the ground station faster after leaving the cloud. When comparing the results of these missions, officials found that the T-33 samples were far better than the B-29 and six times as strong in many instances. Colonel Fackler's final report of air participation concluded with the recommendation that either F-89 or F-9); aircraft replace the T-33. The latter, while presenting a number of advantages over bomber aircraft, did not have the altitude capabilities desired for sampling. In addition, the report recommended that sampler aircraft be assigned to the Special Weapons Command permanently in order to facilitate installation of instruments , U7 _ Operation TUMBLER/SNAPPER Within a few days the Special Weapons Command received word that another continental test program would be conducted at the Nevada Test Site in the spring of 1952.
