🇺🇸 USAF — Project Blue Book
In May 1967, a witness in Sullivan, Indiana, reported an unidentified aerial phenomenon. The document, a technical questionnaire from the U.S. Air Force, seeks details about the object's appearance, movement, and environmental conditions. The witness described the object as bright but did not provide information about its shape or size. The Air Force requested additional information, and in this case, the witness claimed that the "aliens" left behind a "box of angel hair." Despite investigation efforts, the object could not be identified, and the material was never confirmed. The Air Force thanked the witness and offered assistance for future sightings.
