one of which can stop the firing operation and some of which are temporary or delay~type systems, such as the Transmissometer which will stop the operation for rain but which will permit it to proceed after passage of the rain. will be "lockouts". Other "go-no go" systems The operation of these interlocks indicate more serious trouble and the operation must be delayed. A delay greater than 24 hours automatically means a 4-day delay because of the cryogenics problem. The success of several experiments is dependent upon the early recovery of records or samples. It is expected that every effort within the nad~Safe limitations will be made to make these specific recoveries within the first 6 hours after shot time. Priorities will be established by the Scientific Deputy, JTF 132 in coordination with the Commander, TG 132.1 based on the value of the respective scientific information involved. After this early recovery no additional recovery will be permitted until M‘l day, dependent upon Rad-Safe conditions. The early recovery operations will be helicopter only, with all recovery operations based from the Rendova. No recovery will be permitted during the hours of darkness. Those samples recovered from Eniwetok Atoll requiring rusk delivery to laboratories in the ZI will be flowin aircraft from the flight deck of the Rendova to Kwajalein and there transferred to “sample return" aircraft staged from Kwajalein to the ZI via Hickam. i
