A ground-breaking memoir from Luis Elizondo, the former head of the Pentagon's Advanced Aerospace Threat Identification Programme, revealing what is really known by world governments about UFOs and UAP. The former head of the Pentagon program responsible for the investigation of UFOs - now known as Unidentified Anomalous Phenomena (UAP) - reveals long-hidden truths with profound implications for not only national security but our understanding of the universe. Luis 'Lue' Elizondo is a former senior intelligence official and special agent who was recruited into a strange and highly sensitive US Government program to investigate UAP incursions into sensitive military installations and air space. To accomplish his mission, Elizondo had to rely on decades of experience gained working some of America's most sensitive and classified programs. Even then, he was not prepared for what he would learn, and the truth about the government's long shadowy involvement in UAP investigations, and the lengths officials would take to keep them a secret. The stakes could not be higher. Imminent is a first-hand, revelatory account inside the Pentagon's most closely guarded secret and a call to action to confront humanity's greatest existential questions.
