NEW YORK TIMES BESTSELLER • Impeccably researched, this riveting journalistic investigation separates fact from fiction, and documents the unexplained mysteries of—and government reactions to—actual UFOs. “A treasure trove of insightful and eye-opening information.”—Michio Kaku, PH.D., bestselling author of Physics of the Future Leslie Kean, a veteran investigative reporter who has spent the past ten years studying the still-unexplained UFO phenomenon, reviewed hundreds of government documents, aviation reports, radar data, and case studies with corroborating physical evidence. She interviewed dozens of high-level officials and aviation witnesses from around the world. Among them, five Air Force generals and a host of high-level sources—including Fife Symington III, former governor of Arizona, and Nick Pope, former head of the British Defence Ministry’s UFO Investigative Unit—have written their own breathtaking, firsthand accounts about UFO encounters and investigations exclusively for this book. With the support of former White House chief of staff John Podesta, Kean lifts the veil on decades of U.S. government misinformation about this mysterious phenomenon and presents irrefutable evidence that unknown flying objects—metallic, luminous, and seemingly able to maneuver in ways that defy the laws of physics—actually exist. With a Foreword by John Podesta “The most important book on the phenomenon in a generation.”—Journal of Scientific Exploration “Written with penetrating depth and insight, the revelations in this book constitute a watershed event in lifting the taboo against rational discourse about this controversial subject.”—Harold E. Puthoff, PH.D., Director of the Institute for Advanced Studies at Austin “Kean presents the most accurate, most credible reports on UFOs you will ever find. She may not have the final smoking gun, but I smell the gunpowder.”—Miles O’Brien, science correspondent for PBS’s NewsHour
