An Air Force major is ordered to approach a brilliant UFO in his Phantom jet over Tehran. He repeatedly attempts to engage and fire on unusual objects heading right toward his aircraft, but his missile control is locked and disabled. Witnessed from the ground, this dogfight becomes the subject of a secret report by the U.S. Defense Intelligence Agency. In Belgium, an Air Force colonel investigates a series of widespread sightings of unidentified triangular objects, sending F-16s to attempt a closer look. Hundreds of eyewitnesses, including on-duty police officers, file reports about the incident, and a spectacular photograph of an unidentifiable craft is retrieved and analyzed. Here at home, a retired chief of the Federal Aviation Administration's Accidents and Investigations Division reveals the agency's response to a thirty-minute encounter between an aircraft and a gigantic UFO over Alaska, which occurred during his watch and is documented on radar. Now all three of these distinguished men have written breathtaking, firsthand accounts about these extraordinary incidents. They are joined by Air Force generals and a host of high-level sources who have agreed to write their own detailed, personal stories about UFO encounters and investigations for the first time. They are coming forward now because of Leslie Kean, an investigative reporter who has spent the last ten years studying the still unexplained UFO phenomenon. Kean reviewed hundreds of government documents, aviation reports, radar data, and case studies with corroborating physical evidence. With the support of former White House Chief of Staff John Podesta, Kean draws on her research to separate fact from fiction and to lift the veil on decades of U.S. government misinformation. Throughout, she presents irrefutable evidence that unknown flying objects -- metallic, luminous, and seemingly able to maneuver in ways that defy the laws of physics -- actually exist.
