/ a ” a4 c@fimander was in position to divert it to a safe position and inform the Task Force Commander. Aircraft whose positions were not as critical as the effects aircraft were directed to a pre-planned H-Hour orbit by the Air Operations Center Controller and timed around this orbit in order that they might be at the pre-determined H-Hour position at time of detonation. These air= craft were positioned by the Air Operations Center Controllers in mich the same manner as the Controllers monitored the effects aircraft with the use of a pre-planned orbit and definite time check points. Since the effects of the detonation on these aircraft was not considered critical, they had no abort procedures; however, the positions had to be accurately maintained in order for them to receive the desired test results. This category of aircraft included Search and Rescue (SAR) aircraft, sampler controller aircraft, photographic aircraft and instrument carriers. During the last six (6) minutes prior to a detonation the Commander of Task Group 7.4 kept a constant check on the accurate positioning of all aircraft in the test array. During this period he was in constant touch by "hot line" with the Commander, Joint Task Force SEVEN and the firing party. The Commander, Task Group 7.4 kept the Commander, Joint Task Force SEVEN and the firing party briefed on the safety of the aircraft positions. If necessary, this "hot line" was also his method for obtaining information about shot delays or cancellations. Methods of control in the Bikini Air Operations Center aboard the USS BOXER were the same as those used in the Eniwetok Air Operations 125 AFWL/HO | ~~ —_
