Project Blue Book

Project Blue Book was not the only investigation of unidentified flying objects by the United States military but it was probably the most famous. It was commissioned in 1952 and ceased all operations by January of 1970. Over the life of Project Blue Book several important figures were associated with the study, including Dr. J. Allen Hynek and Captain Edward Ruppelt. After almost two decades of Blue Book investigations the US Air Force collected over 10,000 reports of UFO activity and were able to adequately explain the vast majority.
