Official description
Box 186 file 319.1, Flying Discs (filing year 1949, document period mid-1947). Lowry Flight Service Center, Lowry Air Force Base, Denver Colorado correspondence covering reports of disc-shaped aerial objects observed across the western United States during the Kenneth Arnold-era 1947 wave. Marked DECLASSIFIED at release.
Editor's context
This file predates Project Sign (officially organized December 1947) and is one of the earliest institutional intelligence collections on what would later be called UAP. Its presence in PURSUE Release 01 establishes a continuous documentary chain from the 1947 wave to the present catalog. The file is large (approximately 72 MB) and predominantly contains period-typewritten cables and witness summary forms with redactions and handwritten margin notes.
Prevailing explanation
What scientists and analysts generally think
The 1947 wave is now generally understood as a combination of misidentified high-altitude balloon experiments (including the classified Project Mogul), conventional aircraft, and the social-cognition effects of the Kenneth Arnold sighting saturating the press. The Lowry file is consistent with that historical reading: most reports it summarizes have plausible conventional explanations on second look.
In the margins
Transcribed redactions, stamps, and handwritten markings, the paratext of the file. Often the most human part of a declassified document, and worth reading on its own.
