Project 10073 Record Card and Sighting Summaries, April 1956

This document is a compilation of UAP sighting reports from April 1956, centered around a Project 10073 record card for an incident in Tacoma, Washington, on April 30, 1956. The primary report details a sighting by a civilian witness who observed a slim object, approximately 18 inches long and 2 inches wide, with red lights on each end and no wings. The object was heard making a sound similar to a piston engine and was observed for three minutes as it traveled east and then turned north. The official conclusion for this specific case was that the sighting was likely an aircraft. The document also includes a series of 'Information Only' summaries of various other sightings reported throughout April 1956 across the United States and Canada. These include reports of mysterious lights in Cumberland Beach, Ontario; a metallic object seen by GOC filter center personnel in Baudette, Minnesota; a dome-topped, saucer-shaped object photographed by an Air Force woman in Manomet, Massachusetts; a spinning disc in Coffeyville, Kansas; a half-egg-shaped object in El Monte, California; a long silver object in Phoenix, Arizona; and a 'bonfire in the sky' in East Mansfield, Massachusetts. Additionally, the document contains a summary table of sightings for May 1956, categorizing various reports by location, observer, and evaluation, with many being attributed to astronomical phenomena, balloons, or aircraft, while others were marked as having insufficient data. The document provides a snapshot of the investigative process for UAP reports during this period, highlighting the variety of civilian reports received and the subsequent attempts by the Air Technical Intelligence Center to categorize them.
