0018933 the rockets on Sally and Wilma were launched, but the obscuring cloud cover prevented observation of their trajectories, The rockets on Mary did not launch and later inspection showed that one launcher was inoperative, one elevated without rotating and two elevated and rotated. Two nose cones from the Sally rockets were recovered by boat and the others were lost. The closures on the cones recovered were intact but water had leaked ing There was a small amount of activity in the water and on the filter and the filter sample was returned to the ZI for analysis. It was identified by the name Whiskey 6 (see Table B. 3). 6 samples were taken from the cloud at times between 1-1/2 hours _ and 26 hours post shot time (see Table B3), Both the wing tank and the coincident samplers were operative on each flight, In preparing the height line flight program for this shot, it was intended that 1 WB-50 would collect 1000 foot samples at 4, 6, 8, 10 and 12 hours with a second WB-50 standing by on the ground to take over the mission, if necessary. No sampling flight was scheduled for D / 1 day. The first aircraft encountered fallout at H 4 4 hours ona bearing of 320 degrees at a distance of 42 miles from surface zero and a sample was collected, Due to deposition of damp fallout material on the nose of the air- craft, a dose of 1.5 r, (read on an electronic integrating dosimeterj'‘sas me accumulated at the bombardier's position during the sampling run, The 58 5¢
