Gi: Party completes the Parry Island check out. From 0530 to 0630 a DD boat will pick up the Firing Party and rendezvous with The Firing Party will then transfer to the the Estes by 0800. Estes. The basic firing mechanism for detonating the Mike device is a clock-activated system located on Elugelab. Depend-~ ing on the results ofsextensive tests to be made prior to 1 October, the timing and firing sequence may be started by remote r-f control. The purpose of the tests is to insure that the remote system will be as safe as is humanly possible to make it. As an alternate to the remote starting, a straight clock-timed start is contemplated, i.e., with no r-f start control. <A safety switch in series with the arming and firing cable may be located on Parry Isiand in order to provide an additional sefety feature for the Firing Party. Two television channels be- tween Elugelab and the USS Estes will present pictures of the cryogenics monitoring systems and the timing, power on, arming and firing circuits. Within these two channels sufficient cross channel information will be presented to provide a back-up should one channel go out or become unintelligible. In addition, a sep- arate radio channel is provided such that the firing system can be stopped at any moment up to zero time. There are also several we "go=no go" interlock systems built into the firing circuit, any
