Raydist data was recorded by that aircraft. Therefore, no On BRAVO, the ELAINE ONE (B~36 effects) crew reported a bright red glow through the aluminized asbestos shields over the cabin windows during the peak of the thermal phase, In the aft cabin, a great deal of smoke was produced by the ; burning of the sponge rubber pads around the rims of both lower blisters. When the shock wave arrived, the controls were described as "free-float— ing" for a few seconds. A sharp bump similar to a thumderstorm was noted, All equipment and instrumentation operated perfectly during the shot period. Jet engine tail-pipe temperatures, normally about 500° ¢, rose to 750° C shortly after shot time. temperature, however, was much higher.
