Executive Summary
Across multiple late-October dates in the 1970s and 2000s, witnesses in the United States have reported large, low-altitude, low-noise craft moving slowly over urban and rural areas. The most-cited incidents include the October 1973 Coyne helicopter encounter (Mansfield, Ohio) and the October 31 2008 Lake Erie sighting. None has produced conclusively identified hardware. This dossier is maintained as an open-questions case file.
The Hidden Truth
What the headlines won't tell you
The Coyne incident remains one of the best-documented military aircrew UFO encounters in U.S. records. Four Army Reserve aviators independently reported the same near-collision and were debriefed under oath. Their statements survive in the AAWSAP archive and were referenced in the 2021 ODNI preliminary UAP report.
