element's relative position. Continuous positions will be given to both CASSIDY ONT and TIGER aircraft until CASSIDY ONE makes positive radio and IfF contact with TIGER aircraft. CASSIDY ONE will then assume control, CASSIDY ONE will turn control of the TIGER element over to sampler Con- troller, call sign CASSIDY TWO on VHF Channel "E", CASSIDY TWO will direct the TIGER aircraft sampling mission. Upon completion thereof, CASSIDY TWO will instruct the TIGER element to return to "F" Channel’and ¢all CASSIDY ONE, CASSIDY ONE will rendezvous the TIGFR element and give the lead air’ eraft a bearing and range to BOUNDARY TARE or DIRTY FACE, naintaining control until BOUNDARY TARE or DIRTY FACE establishes radio and IFF contact with TIGR aircraft and accepts positive control. d. In the evont of an F~84 emergency, CASSIDY ONE will direct STABLE ONE to tho aircraft in distress, on Channel "F", If the SAR aircraft is not in the inmediate area or cannot be contacted, CASSIDY ONE may direct another aircraft in the area to orbit over "the distressed aircraft until the SAR aircraft arrives and assumes control of the rescue operation. ~ BOUNDARY TARE will continually monitor the sampling operation on VHF Channel "EY and YF", an@ standby on "D" for emergency. All aircraft positions will bo monitored by BOUNJARY “ARE throughout the saz-pling operation to assist CASSIDY in positioning: any aircraft, on. request, orto take over control of SAR operations if required, BOUNDARY TARE will provide - CASSIDY with any weather or rad/safe information requested on Channol "E" or "PF", If the sampling area drifts from BOUNDARY TARE's radio coverage, communications between BOUNDARY TARE and CASSIDY will be established on the HF air ground Channol J-410 or through use of a VHF relay aircraft. f. CASSIDY TWO (2) will provide BOUNDARY TARE with radiological reports cach 30 minutes, as outlinod in Appendix 1. HF air-ground channcl J-410 or VHF Channo] "E" will be used for this reporting. g. CASSIDY ONE (1) will be instructed by BOUNDARY TARE to switch . to Channel "B" for the following time hacks: — (1) H-2 hours 2 minutes for H-2 hour time hack, (2) 4.1 hour 2 minutes for Hel hour time hack, (3) 32 minutes for H-30 minutes time hack, (4) +3 minutes ani remain on B until aftor H hour. h. When CASSIDY has completed its mission, to inclule directing the B-36 or Canbera samplers, if required, BOUNDARY TARE will vector CASSIDY to Eniwetok and maintain positive control until DIRTY FACE estab- lishes radio and ITF contact with CASSIDY, At this timo, DIRTY FACE will assure positive control of CASSIDY and vector the aircraft to base for landing. i. In the event of a cloud movement toward Tniwetok, BOUNDARY TARE may direct DIRTY FACE to send F-84's direct to CASSIDY ONE (1). ASSIDYONE (1) will normally send doparting F.-84's to DIRTY FACE by way of BOUNDARY TARE. If doamed more practical, considering fucl remaining, cloud position, etc., F-84's may be sent directly tack to DIRTY FACE or by way of . the Control Destroyer. such action. Tasca RUER 7-4 NO. 1-54 ANNEX ugGn BOUNDARY TARE will be iumediately notified of any , Gu.2.- ~
