rrr 1. \ Zi (a) The WB«29 radio oporator 11 immediately notify the ENIV"TOK £06 of the ome. ney on Circuit J~411 and announce tho pilots: intontions. The AOC will initiate required orergoncy action, -moaintiining contact with tho aircraft in distress on J=411 until VAF contact is possible, The USS ESTES will be located in the BIKINT Aroa during shot periods, The CIC will continually monitor VHF Channel "D" and HF Frequency 8364 kcs. WB~29's may contact this station for omorgoncy assistance, including GCI rader voctors, VHF/DF stoors and SAR intercept, at the discretion of the aircraft commander. (e) Although crews will be thoroughly briefed on all aspects of cach mission as spocified in paragraph 3b(1) above, the following cloud tracking infor~ mation is provided for planning purposes: 1. Flight #1 (H to H/12 Hours): This flight is to detormine the charactoristics of the radiological hezard likcly to drift and fall out on ENIWETOK or UJELANG 2ZTOLLS and the hazard upwind from the shot atoll, This aircraft will take-off, climb to 10,000 fect and hold at a position 90 mutical intles West of Ground Zero until H/5 mimtes. Th: aircraft will then begin eae 10,000 foot racetrack holding pattorn of approximately five (5) hours duration, the eastern edge of which will be 50 nautical miles West of Ground Zero. | This pattern will extend 100 nautical miles from north to south and 25 niles from east to west (sce Appendix 1). Upon encountering radiation, is to be shifted westward to edgo of the radiation field. this phase of tho mission, a the entire pattern follow the lcading Upon completion of search upwind from the shot atoll will be made in a 30 degree sector with apex on ground zero and centered on the aver-~ age prevailing casterlies. "KE" type search pattern at 10,000 feet will be employed, Specific inst= ructions for this mission will be forwarded by CJIF SEVEN to CIG 7,4, ATTN: Commander, Test Services Unit, not later than H minus eight (8) hours, 2. , . 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 southcast quadrant and the hozerds existing on, or near, air routes of interest to commands extcrnal to the Task Force Aroa of responsibility (Appendix 2), "E" typo flight patterns at 10,000 feot will be employcd,. Search of air routes will be at 10,000 foet and aiong the routes, or through ‘the area forecast to be upwind from such routes, for representative distances as determined by the ostimated Limits of accuracy of the air RADEX, The attempt here will be to dotermine the contamination status of tho air on the routes, or of the potentinl hezards likely to drift across the routes. The air routos -of interest are those through Wake and thc Marshal Islands, Specific instructions will be forwarded by CJTF SEVEN to CTG 7.4, ATIN: Communder, Test Services Unit, not later than H plus four (4) hours, !
