Project 10073 Record Card — Sighting Incident, Lima, Ohio, November 1957

This document contains a Project 10073 record card and associated technical information sheets regarding a UFO sighting reported in Lima, Ohio, on November 6-7, 1957. A local newspaper reporter contacted the Air Force on behalf of several citizens who observed a round, red, glowing object at a very high altitude. The object was described as moving slowly and was observed for approximately seven minutes. The Air Force investigation concluded that the sightings were likely caused by lighted weather balloons released by a weather unit at Sulphur Grove. The report includes detailed calculations of wind speed and direction, noting that winds from the south-southwest at 30 knots would have carried the balloons to the vicinity of Lima and Uniopolis at the exact times the sightings were reported. The file includes handwritten notes, diagrams of the balloon trajectory, and a completed technical information sheet from a witness who described the object as having a red glow and being fuzzy or blurred in appearance. The witness, a reporter, noted that the object moved slowly away and was observed through binoculars. The final assessment by the Air Force was that the phenomenon was a balloon.
