July 10, 2026 · 17 documents · 23 videos

Fourteen documents that connect early USAF UFO science with modern range-safety reporting. The 1948 Project Sign progress report from Wright-Patterson (Project “Sign” / HT-304) tabulates the first systematic USAF review of flying objects. Companion DoW PDFs cover 1948–49 incident analyses, 1966–67 DAF review of Project Blue Book, and 1954–55 joint U.S.–Canadian aviation/UFO correspondence. Contemporary operational material includes 2019–2020 range-fouler debriefs from the eastern United States and Atlantic operating areas. DOE adds a 1949 Los Alamos conference on aerial phenomena and a 2015 Pantex unidentified-object incident report; CIA memos cover 1955 unconventional-aircraft studies. Twenty-three videos packaged separately.
