The 509th Composite Group and the UFOs/
Tinian, Guam, and Saipan
In May 1945, the 509th Composite Group started arriving on Tinian Island in the Mariana Islands. Tinian Island is located between Guam to the south and Saipan to the north. Operating out of North Field, Tinian Island, it was the 509th Composite Group that dropped the two atomic bombs on Japan on August 6 and 9, 1945, at Hiroshima and Nagasaki.
During the summer of 1945 naval air search radar picked up large groups of unidentified objects traveling over the open sea over an area between Guam and Saipan. These objects were moving at over an estimated one thousand miles per hour.
See the information below.
 The 509th Composite Group and the UFOs
During the latter part of the month of May 1945, the greater part of the 509th Composite Group arrived on Tinian Island in the Mariana Islands, western Pacific Ocean. The movement was done via C-54 or B-29 aircraft following a route from the United States to Hickman Field, Hawaii, to Johnston Island, to Kwajalein Island in the Marshall Islands, and then on to Tinian Island. (1)  The first C-54, number 9009, of the Advanced Air Echelon flew from Kwajelein to Tinian on May 22, 1945.

Summer 1945; at sea between Guam and Saipan
A Naval Radar Officer reports:
During the summer of 1945, at sea between Guam and Saipan, our air search radar on several occasions picked up a large group of pips approximately one hundred miles away on a course that would bring them directly overhead. We challenged them but got no response. Their speed on our plot indicated over one thousand miles per hour. These groups passed overhead at approximately two thousand feet and showed up on the radar screen as definite solid (not fuzzy) objects. When our visual spotters reported there was nothing in view, I personally went out and searched the sky with no luck. Our gear was carefully checked and calibrated and was in good order. These were definitely not ioized clouds, inversions, sea gulls, mechanical defects, or any other common explanations. After many months of operating radar gear one knows when they have a definite solid object on the screen, and for my money these were solid although invisible objects.
