Project 10073 Record Cards and Technical Information Sheets

This document is a collection of Project 10073 record cards and U.S. Air Force Technical Information Sheets documenting various unidentified aerial phenomena sightings reported in May 1956. The records focus on two specific incidents in Dayton, Ohio, as well as several other reports from across the United States and Canada. On 22 May 1956, a round object compared in size to Jupiter was observed in Dayton; it was later determined to be a weather balloon launched from the Sulphur Grove weather station. On 31 May 1956, a high school student in Dayton reported a bluish, tear-drop-shaped object with a short tail, which was estimated to be ten feet long and observed for five seconds. This object was officially concluded to be a meteor. The document also includes press clippings and correspondence regarding other sightings, such as a report from Jacksonville, Florida, involving a bus passenger, and various accounts from California and Utah. These reports highlight the diverse nature of UAP sightings during this period, ranging from identified weather balloons and meteors to anecdotal accounts of brilliant, fast-moving objects. The Air Force utilized standardized questionnaires to gather detailed information from witnesses, including time, location, weather conditions, and physical characteristics of the objects, to facilitate their evaluation process.
