This publication contains Air Force intelligence documentation from Project SIGN, a classified investigation into unidentified flying objects conducted in 1949. The primary account describes a sighting near Biloxi, Mississippi on August 6, 1949, at 2000 hours. A 1st Lieutenant stationed at Keesler Air Force Base observed a bright yellow, spherical object approximately two feet in diameter, traveling at an estimated 600-800 mph at 1,000 feet altitude. The object remained visible for approximately twenty seconds before disappearing instantaneously without visible exhaust or sound. The witness, an atomic energy instructor and bombardier, was classified as an excellent, reliable observer. A witness present was identified as Mrs. Helter Prabis. The document includes systematic investigation protocols covering object characteristics, observer qualifications, weather data, and procedural checklists for further inquiry. A related sighting near New Orleans, Louisiana is referenced. Documentation concludes with official routing and investigative records from the 9th District Office of Special Investigations dated October 13, 1949.
