In addition, the forecast OZ winds up to maxims significant altitude will be passed for ine formation-to CTG 7.3 and TU 7 (Radsafe CENTER). 5. The sample return plan and communication channels will be checked for readiness, Sample return aircraft will be checked for readiness, 6. The transient ship plot will be brogghbup to date based on reports from the D minus 1 day P2V sweeps. for Deday if required, 7, idditional P2¥ sweeps will be requested ss At H minus 8 hours, CT 7.4 will be directed to conduct Flight #1, WB=29 Cloud Tracking from H plus 2 to H plus 14 RKours.
