Brad Sparks:
April 12, 1953; Sweetwater, Nevada (BBU)
4:10 p.m. (MST). Ten round flat metallic colored objects changing formation traveled at an estimated high rate of speed on a heading of 110 at an estimated altitude of 7,500 ft. No trail, sound, or exhaust were noted. Objects passed under the right nacelle of the observers C-47 type aircraft, and were observed by the co-pilot. He took control of the C-47, and turned to the right in a tight 300 degree turn for a better view of the objects. Objects were then picked up unassisted by two more members of the crew. The objects were observed in a right turn of greater radius than that of the C-47, and at a lower altitude. The objects were observed for approximately 120 degrees of their turn, and disappeared on a heading of 300 degrees. Observers were unable to estimate the speed of the objects because of the distance and the objects large radius of turn. (BBU, Sparks; McDonald list)

Fran Ridge:
At first, this very interesting and brief, once-SECRET, case summary almost gets lost in the shuffle of bigger cases but paints a picture of an encounter much opposed to the Air Force conclusion of aircraft as the possible cause. Then Dan Wilson uncovered 20 more documents.
