Short but a great document. It contains details regarding sighting of a round shiny object streaking across the New Mexico skies on 05 June 1952 at 18.45 hrs by sergeant T.H Shorey of 4925 th Atomic Test Group, Kirtland AFB at his home at 521 South Cedar Str, Albuquerque, New Mexico. His house is located almost in the center of the city. According to the witness the object was clearly round in shape but of indeterminable size. With a shiny luster, noiseless and no trails.

The most important part of the testimony is the speed of the object described as being 5-6 times faster than a F-86. The visibility was great and at the moment (60 miles) of sighting the object flew above a B-29 or B-50 which at the time was about 10.000 feet in a easterly course. Judging by the object of reference, the witness claimed that the UFO must have in a much greater altitude and it covered the remaining distance across the horizon in few seconds. The witness was in engineering field therefore his observation from a mechanical viewpoint should be considered as fairly reliable.

As the OP said, this document is very short and nothing more to add in regards.
