The Roswell crash site. The Phoenix Lights. Area 51. Sightings, conspiracies, glimpses of the unexplained. Decades of questions unanswered. Forget what you think you know about Unidentified Flying Objects. On 25 June 2021, the Pentagon released an historic report confirming 144 incidents of 'unidentified aerial phenomena' (UAP) with no easy explanation. The US Navy and Air Force have confirmed ongoing sightings of bizarre objects moving at blinding speeds - often around nuclear and defence sites. Barack Obama has publicly acknowledged the concern. Luis Elizondo spent an accomplished military career hunting drug traffickers and terrorists, before being posted as Director of US Government's highly sensitive Advanced Aerospace Threat Identification Program (AATIP) in 2008. In that capacity, Elizondo led an international effort to study UFOs around the world. Shocked by what they found, Elizondo told his commanding officers: the world needs the full truth. When Elizondo's superiors refused, he resigned his post in order to go public. Since then, he has led the global disclosure effort. - Are we alone? - Are governments in possession of wreckage? - What do we know about the science and tech of UAP? - Have UAP compromised our nuclear weapons caches? - What's inside a UAP? - Where do UAP go between sightings? Do they have a base, or do they live among us? - And the biggest questions of all: Who. Are. They? As a civilian with high-level national security clearance, Elizondo is widely viewed as the world's most credible authority on UAP and UFOs. This memoir reveals groundbreaking - even shocking - details of what AATIP learned, and the profound implications, not just for humanity but for everything we think we know about our lonely place in the universe.
