Project 10073 Record: Sighting near Brockton, Mass., 27 August 1950

This document, dated 25 September 1950, details an investigation by the 1st District Office of Special Investigations regarding an unconventional aircraft sighting near Brockton, Massachusetts. The incident occurred on 27 August 1950 at 1830 hours. The primary witness, a private-licensed pilot identified as EARLY, reported observing a shiny, white, spherical object while flying. The witness estimated the object to be approximately twenty feet in diameter and noted it was traveling at a high rate of speed in an easterly direction, at least 1,000 feet below his own aircraft. The witness reported that the object had no visible projections or irregularities on its surface, produced no exhaust smoke, and made no unusual noise. He compared its speed to that of jet planes he had observed at low altitude at Quonset Naval Air Station. The witness also indicated that he pointed out the object to a twelve-year-old passenger from Berkley, Rhode Island, after the object had disappeared from sight. The report notes that the witness believed the object could not have been windblown, as it maintained a steady course despite the southerly wind. The official conclusion reached by the project was that the sighting was a balloon observation. Following the receipt of this report, the District Office determined that no further investigative action was required, citing AFCSI Letter No. 85, dated 8 February 1950.
