Project Blue Book was a secret investigation launched by the United States Air Force to study thousands of UFO sightings during the Cold War. The program examined more than 12,000 reports to determine whether unidentified objects posed a national security threat.
Officials concluded that most sightings were caused by natural phenomena, aircraft, or misidentified technology, and found no scientific evidence proving extraterrestrial visitation. However, hundreds of cases remained unexplained, continuing to fuel debate among researchers and UFO enthusiasts.
Decades later, declassified files from Project Blue Book still shape modern discussions about UFOs and the possibility of alien life.
