ae ’ ° 8 An “== survey instrument of the scintillation counter type will be made available and will be forwarded by JTF SEVEN Rad/Safe Officer to WB-29 operational personnel for additional RADIAC backup. 9s In-flight reports on radiation will be made in conjunction with the standard weather reporting messages uscd for weather reconnaissance flights. Special reports are to be transmitted for any positions where radiation intensity reaches a maximum along a segment of the flight track, re~ gardless of whether or not such positions coincide with points of regular 100-mile weather reports, Additional special reports should be made at critical positions in the flight trak, such as positions which define a cloud boundary, a turn out point, or eny other unusual situation. (2) Heavy Particulate Sampling Sorties: (a} One (1) WB-29, call sign WILSON ONE, will take-off at approximately H-5 hours. Exact take-off time will be specified in Annex "C", "Mission Execution Schedule", This aircraft will contact the Eniwetok A0C on VHF Channel "C" and on HF Circuit J-410 inmediately after take-off. The aircraft will perform weather reconnaissance within a 30 mile radius of the Iniwetok Area and report any significant weather to the AOC, WILSON ONE will then proceed to Bikini reporting weather enroute. When 90 miles out from Pniwetok, WILSON ONE will be instructed by the 40C to call the Command Ship CIC for control and further instructions on VEF Channel "F", The Command Ship Controller will instruct WILSON ONE to report any further significant enroute weather, over VHF Channel "F", or HF Circuit J-410. WILSON ONE will then be instructed to perform local wea- ther reconnaissance in the Bikini Area and to per- form an "Qpwind" weather run culminating in an H- hour position as required in Annex "D", "H-Hour Positions and Flight Patterns". Immediately after H-hour, WILSON ONE will be instructed to change to VHF Channel "4'', At approximately H /# 1:00 hours, ~ WILSON ONE will be directed by CASSIDY to conduct the Heavy Particulate Sampling Operation. The time of this eperation will be decided by the Scientific Director in the Control B-36, WILSON ONE will also be provided all significant rad/safe frecasts, prior to the sampling operation, by the CIC Controller. Safeguarding of the aircraft and crew, however, will be the responsibility of the Rad/Safe monitor aboard WILSON ONE, After the sampling operation is completed, WILSON ONE will be vectored back to ENIWETOK by the CIC Controller, When 90 miles out from Ini- wetok, WILSON ONE will be instructed to call the Mniwetok AOC on VHF Channel "C" for control and fur~ ther instructions. The Iniwetok AOC will vector WILSON ONE to Mniwetok for landing. TASK GROUP 7.4 OPRS ORDER NO. 2-54 ANNEX M M~5
