Project Blue Book Investigation (1952-1969)
The United States Air Force launched its most comprehensive UFO investigation program, documenting over 12,000 reported sightings across America. The project gained particular attention during the 1952 Washington D.C. incidents, when multiple radar operators tracked unknown objects in restricted airspace. Military investigators collected physical evidence, interviewed thousands of witnesses, and analyzed photographs and film footage. While officially concluded with many cases labeled as “unexplained,” numerous Air Force personnel later claimed that the most compelling evidence was deliberately excluded from public reports. The project’s extensive documentation provided researchers with valuable data about patterns in UFO encounters.
