Kwajalein, arrived over the ship and called the USS MT. McKINLEY about an hour before dawn. General Kepner called in a few minutes later and exeellent radio contact between the two planes in the air and the two ships on the surface was established. One development, which had been anticipated, was the failure of radar to identify different aircraft at an altitude of 14,000 feet when about two (2) miles apart. Only one “blip” showed up for the two aircrafte lt was thus established that the usefulness of radar in plotting the position of several aircraft on test days was limited. On subsequent mornings, aircraft were directed over the target until personnel aboard the USS MT. McKINLEY were able to coordinate their work much more effectively. The Combat Information Center personnel developed ways and meana of exercising more effective control over the aircraft in the area. Other members of the staff were at their posts during these early moming exercises, and perfected their operations to a point where each officer was able to perform his duty without hesitation. These exercises also gave the “beeper” pilots aboard “Mother aircraft" an opportunity to develop more accurate control over the drone aircraft under conditions which were expected on test days. Practice landing of drone aircraft on Eniwetok developed further proficiency on the part of the “beeper” pilots, and all aircraft personnel were given their first opportunity to take an active part in the early morning exercises. By the time "P" day had arrived, the process of getting up in the middle of the night, taking off to the target area, and getting on station for a simulated “shot" a few moments before dawn, became routine procedures Seetion VIII 43 ~
