Project 10073 Record Card and Air Intelligence Information Report — 27 April 1952

On 27 April 1952, at approximately 2000 hours, an Air Force Captain stationed at Selfridge Air Force Base, Michigan, observed a large, kelly green, ball-shaped light in the sky. The witness, who was walking in an easterly direction toward the officer's barracks, reported that the object appeared at a 45-degree angle and trailed to a point in the north. The phenomenon lasted for three to four seconds before disappearing. The witness noted that the light was bright enough to cast a reflection in a pool of water along the road, though no sound was heard, and the object moved in a horizontal plane, distinguishing it from the vertical movement of falling stars. Two other officers present at the time acknowledged seeing a light behind them, though they initially assumed it was a beacon. The witness stated they would not have reported the incident if not for the fact that four other sightings had been reported in the area around Selfridge Air Force Base during the daytime. The incident was formally documented on a Project 10073 record card and subsequently transmitted to the Air Technical Intelligence Center at Wright-Patterson Air Force Base under the authority of the 4708th Defense Wing. The official conclusion recorded on the project card categorized the sighting as 'Probably Astronomical METEOR'.
