“I, [Charles] C. Boden, Jr., S/Sgt, A. 116293186, was coming into the Space Control office at approximately 1520 MST, 29 July
I sighted another one at 1625 MST coming from the northwest and departed northeast. It appeared that this particular one had a sort of haze around it and it was only in sight for about three of four seconds. Then three more came over at intervals from 1625 to 1648 MST. All that I saw appeared to be a bright white and shape was circular and one that came over, as it disappeared I thought it was flat and appeared to be turning over and spinning around. The ones that were stationary seemed to be dipping, the sun rays reflecting off and on. They left no vapor trail and no sound. The angle of the objects was approximately 80 degrees on the two stationary and the first three that came through at 1525 MST also at 80 degrees, the other seemed to go right over head. The angle of observation of last four was about 80 degrees. I first saw them at 45 degrees and they passed overhead and we lost them at about 45 degree angle in a [unintelligible] of time of 4 seconds. I called the CAA, Gore Field and reported it to [unintelligible] 1540,
immediately after I had sighted the first three objects.”
