For nearly two decades, the United States Air Force conducted an official investigation into unidentified flying objects. Project Blue Book collected over 12,000 reports, many of which remain unexplained to this day.
Project Blue Book was the third and final phase of the U.S. Air Force investigation into UFOs, running from 1952 to 1969. Headquartered at Wright-Patterson Air Force Base in Ohio, the project investigated 12,618 UFO sightings. While the majority were eventually classified as natural phenomena or misidentified conventional aircraft, 701 cases remained classified as unidentified even after thorough investigation. Among the most compelling cases was the 1964 Socorro, New Mexico incident, where police officer Lonnie Zamora witnessed an egg-shaped craft landing on the outskirts of town, complete with two small figures in white coveralls standing nearby. The landing left physical traces including scorched earth and imprints in the soil. Another notable case was the 1957 RB-47 encounter, where an Air Force reconnaissance aircraft was tracked by an unidentified object that was simultaneously detected by ground radar and observed visually by the crew.
