Project Blue Book: The Largest U.S. Government UAP Dataset (1947–1969) and the Structured Unknowns in SR-14
To the point
Project Blue Book was the Air Force’s official 1947–1969 program to collect and analyze anomalous aerial reports, logging 12,618 cases with 701 remaining unidentified, producing SR-14 as the core statistical study and preserving the data at NARA with access via Fold3 for open, reproducible reanalysis that reveals Unknowns form a structured, nonrandom footprint rather than mere noise.
