This document is a comprehensive compilation of reports, correspondence, and investigative findings related to Project Sign, the United States Air Force's effort to study unidentified aerial phenomena (UAP) in 1948. The archive contains numerous individual incident reports from various locations, including sightings in Utah, Germany, Labrador, Washington, and New Mexico. The reports detail observations of objects described as silver, spherical, cigar-shaped, or glowing balls of fire. Witnesses range from military pilots and radar operators to civilians. The document includes internal routing sheets, teletype messages, and formal requests for analysis from the Air Materiel Command to various field units. A significant portion of the document is dedicated to the 'fireball phenomena' observed in New Mexico, which prompted scientific consultation with experts such as Dr. Lincoln LaPaz of the University of New Mexico. The correspondence highlights the military's struggle to distinguish between conventional aircraft, meteorological events, and truly anomalous objects. Many reports conclude with requests for further investigation, character assessments of witnesses, and attempts to correlate sightings with known flight paths or weather balloon releases. The document reflects the rigorous, albeit often inconclusive, process of military intelligence gathering during the early years of UAP investigation.
The object sighted by the two fighter pilots had the appearance of a flak burst sitting still in the atmosphere and was connected to a curved trail of corkscrew appearance.
