Project Blue Book Case File
Washington, GeorgiaOctober 1959
Summary
On October 12, 1959, residents of Washington, Georgia noticed something strange falling from the sky. A thin, web-like substance drifted down over the town and nearby areas for nearly two hours. Some witnesses described it as gossamer or angel hair. A few strands even had small red objects at the ends that looked like tiny spiders.
Investigators from Robins Air Force Base arrived the same day to document the sighting. They collected samples and interviewed witnesses. One Georgia Highway Patrol officer found two whitish streaks on his lawn about ten feet long and eight inches wide. When he mowed over them, gray dust rose into the air. Samples from his grass tested positive for silver compounds.
Chemical analysis showed that the material contained silver halides, compounds used in cloud seeding operations to produce rain. Research teams from the University of Georgia and a Lockheed facility in Marietta had been conducting cloud seeding experiments in the area that day. The Air Force concluded that the "angel hair" was residue from those experiments. Silver iodide particles can travel miles downwind in mountainous terrain, and they sometimes form visible plumes that witnesses describe as web-like material.
The Air Force closed the case on October 27, 1959, determining that the sighting had been satisfactorily explained as a natural phenomenon resulting from ongoing cloud seeding efforts. The full case file is reproduced below as held by the National Archives, 33 pages.
