for the operation. Back-up aircraft were quickly airborne in all cases and the mission successfully executed, Although there was minor damage to the landing strip at Bikini and considerable debris had to be removed, it was reopened to air traffic at 1700 M Time on Shot Day. The fall-out on inhabited islands during and after ROMEO was minor, and re-entry of Bikini Atoll was accomplished on the evening of ROMEO Day, thereby allowing early sample recovery. of the heavy fall-out went to the northwest as predicted. Most However, a secondary fall-out was noted on the morning of D plus 2 days. In preparation for ROMEO, the Communications Element had to send men to Rongerik on D minus 1 to service and turn on the homer, and to . NAN to inspect, service check and turn on the homer, Racon and VHF transmitters. A PEM or SA~16 rm into Rongerik on D minus 1 was set up for © three Communications personnel, a Rawinsonde team and a radiological safety monitor. This trip was just as faithfully postponed each night, as a direct result of the twenty-four and forty-eight hour shot delays. One phenomenon observed on BRAVO Day was also evident on ROMEO Day: the Kwajalein multiplex circuit went out immediately after the shot and remained out for several hours. In addition, two CW circuits to Kwaja- lein were out for an hour after the shot. Indications were that perhaps some electromagnetic aspect of the detonation was interfering with long- haul circuits. Task Group 7.2 (Army) had the same trouble on their Hono- lulu circuits. Both were out for at least an hour. The Command Ship was again successful in performing its mission dur ing ROMEO. Positive control of all aircraft was continuously maintained throughout the mission. apwisho No radar, IFF or communication failures occurred. PZ
