UFO Observation Report — Green Lake, Wisconsin, April 27, 1967

This document contains a U.S. Air Force Project Blue Book sighting report regarding an unidentified aerial phenomenon observed on April 27, 1967, near Green Lake, Wisconsin. The primary witness, a 17-year-old male, reported observing a solid, sharply outlined object at approximately 2240 CST. The witness described the object as appearing like an 'upside down plate' that changed colors from bright red to orange to white, with a blue glow on the bottom. The object was observed moving slowly north near the ground, eventually descending into a wooded area where it appeared to illuminate the ground with white light. The witness and his companions observed the object for approximately 15 minutes, using 7x50 binoculars to view it more clearly. The witness noted that the object tilted from side to side and moved in a manner that caused him to feel 'too scared to be a wise guy.' The report includes a completed FTD Form 164, a hand-drawn sketch of the object's shape and path, and a personal narrative letter sent to the Project Blue Book Information Office. The Air Force's official conclusion, recorded on the Project 1073 record, identified the object as the planet Venus, noting its azimuth of 300 degrees and setting time of 2240 CST. An investigator's note on the form suggests that the witness should have been asked if they had also observed Venus, implying the Air Force's assessment that the sighting was a misidentification of the planet.
