Project 10073 Record Card — Delavan, Wisconsin, 5 November 1957

This document is a Project 10073 record card and associated military correspondence regarding a UFO sighting reported on November 5, 1957, in Delavan, Wisconsin. A civilian witness reported observing a single, round, bright red object that was spinning and blinking on and off. The object was observed for approximately five minutes, moving from west to east. The report notes that the weather conditions were cloudy with calm surface winds. The military investigation, conducted by the 755th ACWRON and reviewed by the Air Intelligence Center, concluded that the sighting was likely caused by an aircraft. The documentation includes handwritten notes from an evaluator who expressed skepticism regarding the witness's ability to determine that the object was spinning at such a distance, suggesting that the witness's account may have been influenced by other reports. The document also references a potential second witness, a sister of the primary observer, who reportedly saw an object later that same evening.
