IIl 1Ag When Operation rlan 3-586 for the TEAK and OkAnG& events was pub lished on 25 June 1958, the general concept of the NewSiehh operation and of Task Group 7.4 responsibilities became much more crystallized. Several prominent changes were now noticeable, For example, a C-97 and two AV2 aircraft which had not been listed in the original inventory of test aircraft by Task Group 7.4, had now been included for NawSKasL participation. These ai.craft, however, had been listed in the Joint Task Force SxVuN Operation Crder 35=58 on 13 June 1958. ‘The B+36 aircraft were to engage in (1) a project to ascer tain eye effects resuiting from high altitude, high yield detonations, ~ (2) a project to measure and analyze the thermal phenomena resulting from the detonation of nuclear weapons at very high altitudes, (3) a project to determine the modes by which energy is propagated and dis~ sipated from nuclear explosions at high altitudes and to document all visible aspects of the detonation, and (4) a project to photograph at 4J,000 feet the spectrums of both shots as a function of time Juring early fireball growth. The P2V aircraft was to take part in a project dealing with air borne infra-red measurements, the aircraft flying at 25,000 feet. one C-97, sponsored by the sir Force Meaical Center, was to engage in a project with the two B-36's, that of ascertaining eye effects re- sulting from hi,n aititude, nigh yield aetonations, The otner vu-97,
