readiness on_the ground, ene Neg cae ee eet ee DELETED HELETED a Red One was directed into the tail of the cloud at 28,000 feet and plus 105 minutes after burst and collected a very good sample, ‘ ~ A half hour of in-cloud flight time was required due to low cloud intensities, Red Two was directed to the portion of the cloud directly below the overcast at 37,000 feet about 10 mimtes later and observed expected cloud intensity, Hotshot One was directed into the cloud at 42,000 feet and plus 2 hours just above the overcast and collected a good sample despite poor visibility and low cloud intensities, Hotshot Two was put into the cloud at 18,000 feet, 2s hours after burst time and found cloud intensities holding up to the prediction curve, Hotshot Three was unable to reach his assigned altitude of 52,000 feet and in view of the rapidly changing weather and cloud conditions at altitudes below this he was unable to fly on instruments into any portion of the cloud and collect an appreciable sample. Hotshot Four aborted and Cassidy One, therefore, went on in the cloud at 52,000 feet at plus 3 hours and, with the fuel capacity remaining, was able to collect a sample only slightly below the size scheduled for Hotshot Four. While at 52,000 feet, Cassidy estimated the cloud top at 53,000 feet, COPIED/DOE LANL RO . . -72-
