Project 10073 Records: Multiple Sighting Reports, Dayton, Ohio, May 1966

This document is a collection of Project 10073 records and associated correspondence regarding multiple Unidentified Aerial Phenomena (UAP) sightings reported in the Dayton, Ohio area during May 1966. The reports, processed by the U.S. Air Force's Project Blue Book, detail various civilian observations. One report from 11 May 1966 describes a gray object with red and green dots accompanied by a whistling sound. Another report from 15 May 1966 involves a star-like object that zig-zagged before fading, which was later identified by the witness as an aircraft with landing lights. Several other reports from late May 1966 describe lights in the sky, often identified as satellites such as Echo I or Echo II. The correspondence includes letters from Major Hector Quintanilla, Jr., Chief of Project Blue Book, to witnesses, requesting that they complete technical information forms to assist in the evaluation of their sightings. The documents reflect the standard Air Force procedure for investigating UAP reports, involving the collection of witness testimony, weather data, and subsequent classification of the events as either aircraft, satellites, or other natural phenomena.
