Project 10073 Records — Houston, Texas, April 1966

This document contains a series of Project 10073 records documenting various Unidentified Aerial Phenomena (UAP) sightings reported in Houston, Texas, during April 1966. The records include standardized information sheets completed by civilian observers and official summary reports produced by the Foreign Technology Division (FTD). The sightings vary in description, with observers reporting objects ranging from star-like points of light to egg-shaped or round objects, often displaying red, white, or orange colors. Movements described include zig-zag paths, drifting, and rapid speed. Several of these reports were officially concluded to be conventional phenomena, such as aircraft, satellites, or meteors. A significant portion of the document is dedicated to a specific event on April 15, 1966, which generated numerous reports of red lights in the sky. This event was subsequently identified as a hoax engineered by a group of seven Rice University engineering freshmen, led by Robert Vanzant. The students constructed a device consisting of two hydrogen-filled weather balloons, a wood and aluminum frame covered in aluminum foil, and six railroad flares. The device was launched from a campus parking lot, causing widespread alarm and flooding local police and media switchboards with reports. Newspaper clippings from the Houston Post and the Houston Chronicle are included, detailing the students' admission of the prank and their subsequent tour of the Manned Spacecraft Center. Other reports in the file describe individual sightings of objects identified as aircraft or meteors, with investigators noting that no data existed to suggest the objects were anything other than conventional.
