Incident #53 -- near Lake Meade, Nevada -- 28 June 1947

There appears to be nothing astronomical about this incident.

According to the observer, the objects had a speed of 285 MPH and were moving on a course of 120°. Now, since the plane was moving at 285 MPH on a course of 300°, it is possible that the observed motion of the objects was only apparent (since 180° plus 120° equal 300°), and we can conjecture that a cluster of balloons (cosmic ray apparatus perhaps) was observed, the motion of which was merely a reflection of the motion of the plane.

On 28 June 47 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 sighted 5 or 6 white, circular objects at 4:00, 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 was sure the white objects were not birds since the rate of closure was very fast. He was certai…
