-_ 1. 2. (a) -~ The WB-29 radio operator will immediately notify the Fniwetok AOC of the emergency on Circuit J-411 and announce the pilots intentions, The AOC will initiate required emergency action, maintaining contact with the aircraft in distress on J-411 wmtil VHF contact is possible. The USS ESTES will be located in the Bikini Area during shot periods. The CIC will continually moni- tor VHF Channel "D" and HF, Circuit J-410. WB~29's may contact this station for emergoncy assistance, including GCI radar vectors, VHF/DF steers and SAR intercept, at the discretion of the aircraft commander. (6) Although crews will be thoroughly briefed on all aspects of each mission as specified in paragraph 3d(1) above, the following cloud tracking infor- mation is provided for planning purposes: 1, Flight #1 (WILSON #2 - H £.1:05 to H 4 15:00 hours): This flight is to determine the characteristics of the radiological hazard likely to drift and fall out on Eniwetok or Ujelang Atolls and the hazard upwind from the shot atoll. WILSON #2 will take- off at H £ 1:05 hours, climb to 10,000 feet while proceeding to Point "A", (See Appendix 1). WILSON #2 will then begin a 10,000 foot racetrack holding pattern, the eastern edge will be 50 nautical miles West of Ground Zero, This pattern will extend 70 nautical miles from North to South and 15 miles from East to West (See Appendix 1). Upon encountering radiation, the entire pattern is to be shifted westward to follow the leading edge of the radiation field. Upon completion of this phase of the mission, a search upwind from the shot atoll will be made in a 30 degree sector with apex on ground zero and centered on the average prevailing easterlies. "E" type search pattern at 10,000 feet will be employed. Specific inst- ructions for this mission will be forwarded by CJTF SEVEN to CIG 7.4, ATIN: Commander, Test Services Unit, not later than H minus eight (8) YP hours. Flight #2 (H plus 12 hours to H plus 24 hours): This flight is to determine the characteristics of the radiological hazard existing upwind from the native populated atolls in the southeast quadrant and the hazards existing on, or near, air routes of interest to commands external to the Task Force Area of responsibility (Appendix 2). "E" type flight patterns at 10,000 feet will be employed. Search of ‘air routes will be at 10,000 feet and along the routes, or through the area forecast to be upwind from such routes, for representative distances as determined by the estimated limits of accuracy of the air RADEX. The attempt here will be to determine the contamination status of the air on the routes, or of the potential hazards likely to drift across the routes. The air routes of interest are those through Wake and the Marshall Islands. Specific instructions will be forwarded by CJTF SEVEN to CTG 7.4, ATINs Commander, Test Services Unit, not later than H plus four (4) OUTS « TASK GROUP 7.4 OPRS ORDER NO, 2-54 ANNEX M
