Project Blue Book Case File
Chorpus Christi, TexasOctober 1962
Summary
On October 26, 1962, a farmer in Corpus Christi, Texas reported that a piece of translucent material had fallen from the sky and struck his plow. He kept the material and reported the incident, and the Air Force took possession of the fragment for analysis.
The piece was forwarded to the Aeronautical Systems Division at Wright-Patterson Air Force Base in Ohio. Experts there ran a series of tests to determine what it was. They tested it for radioactivity, light transmission, chemical composition, and optical properties. The sample showed no radioactivity above normal background levels. Chemically, it was made of common glass materials, primarily silicon dioxide and calcium oxide with smaller amounts of sodium and other elements.
The lab concluded the material was bottle glass, specifically a low-quality type used in large containers. Technicians found evidence of a sheared gob, a manufacturing technique indicating the glass was made by machine. The Owens-Illinois Glass Company, which examined the sample, determined it likely came from a large carboy or wide-mouth jar, between 5 and 6.5 gallons in capacity. The company believed its Alton, Illinois plant was probably where this particular glass was manufactured.
The Air Force recorded this case as "unknown," though the physical evidence clearly pointed to ordinary bottle glass that had fallen from the sky, most likely having been ejected from an aircraft or dropped from high altitude. The complete case file is reproduced below as held by the National Archives, comprising 8 pages.
