PROJECT 10073 RECORD CARD - LAKE COUNTY, OHIO - 7 NOVEMBER 1957

This document consists of a Project 10073 record card and accompanying Civil Defense minutes regarding a UFO sighting in Lake County, Ohio, on November 7, 1957. A witness reported observing a round, blueish-green object with a metallic appearance, described as resembling a Mexican hat, at approximately 0630 hours. The object was reported to be very low, larger than an airplane, and emitted a sound similar to a quiet generator or a running light meter. The witness claimed the object split into two parts, with one part rising and the other landing on a knoll. Upon returning to the scene with his wife, the witness found the object gone. Civil Defense personnel, including Colonel Leroy John and Lieutenant C. Reinecke, conducted an investigation at the site. During their inspection, they utilized Geiger counters and recorded radiation levels ranging from twenty to one hundred fifty microroentgens in the center of the area, noting a rapid decay of radiation. They also checked a woman's car in the area, which showed readings of twenty to sixty-four microroentgens. The official conclusion on the record card is 'Insufficient Data for Evaluation,' with a note suggesting the report was second-hand, delayed, and potentially attributed to psychological causes.
