U.S. Air Force Technical Information Sheet — Sighting Report, Bay City, Michigan, March 23, 1953

This document is a U.S. Air Force Technical Information Sheet detailing a sighting reported by a lawyer in Bay City, Michigan, on March 23, 1953. The witness, who was lying in bed at approximately 11:32 P.M. EST, observed a flaming, elliptical object moving from right to left across the lower half of a window. The witness described the object as having a greenish, fluorescent color, similar to paint on a clock dial, and noted that it appeared to wobble during its four-second transit. The witness estimated the object's size as being larger than Venus but smaller than the moon, with a length approximately twice its height. The sky was described as hazy with a thin overcast, which the witness noted gave the moon a similar soft outline. The witness explicitly stated that no sound was heard, noting that the windows were closed. Following the observation, the witness immediately checked the time and recorded notes regarding the object's trajectory, color, and appearance. The witness later returned to the window to observe the moon for comparison and took measurements of the room the following morning to document the exact angle of view. The report includes detailed sketches and measurements of the room, the window, and the witness's position. The official conclusion provided by the Air Force on the report form is that the object was an astronomical phenomenon, specifically a meteor, noting that the hazy sky likely contributed to the fuzzy appearance of the object and that its movement was consistent with a meteor. The witness themselves speculated in their report that the object might have been a rocket, jet engine, or incendiary device.
