U.S. Air Force Analysis of Flying Objects in the United States, 1-100

On 28 June 47 [illegible] in a P-51 bound for Portland, Oregon, by way of Medford, Oregon, at approx 1515 CST (course of 300°) and ground speed of 285 MPH, altitude 10,000 ft, approximately 30 miles NW of Lake Meade, Nevada, Lt Armstrong sighted 5 or 6 white, circular objects at 4:00, position altitude approximately 6,000 ft, on a course of 120° and flying at an estimated speed of 285 MPH. The objects were flying very smoothly and in a close formation. The estimated size of the white objects was approximately 36" in diameter. Lt Armstrong was sure the white objects were not birds since the rate of closure was very fast. He was certain too that the white objects were not jets or conventional aircraft since he has flown both. AGENT'S NOTES: Lt Armstrong was very sincere in the explanation and was not the exaggerating type. He merely stated what he saw and drew no conclusions.
