In 1950, two spinning disks flew over Great Falls, Montana, and were filmed on a hand-held camera. Today, those "flying saucers" in the now-famous "Montana Movie" still defy conventional explanation. In the 1960s, UFOs were reported at Minuteman missile silos in Montana. In separate incidents while a UFO was overhead, armed and ready nuclear missiles were suddenly deactivated as missile launch officers watched helplessly. The U.S. Air Force ordered these men never to tell anyone what happened. This book critically examines these and other UFO events in Montana, including reported contact with extraterrestrials. Drawing on recently declassified government documents, historic reports, and first-hand interviews, Ph.D. zoologist and author Joan Bird presents compelling evidence that UFOs are real, have frequented Montana's Big Sky, and have landed in the state. This book also introduces readers to significant UFO incidents in the U.S., to official government investigations such as Project Blue Book, and to major figures in the study of UFOs.
