Charles Lear is the author of "The Flying Saucer Investigators." At its core, it is a book of history. It's about the people involved in the mystery of the flying saucers, mostly the investigators, but also the witnesses, some of whom were profoundly affected. The period covered is what has been called "The Golden Age of Flying Saucers," which begins in 1947, after the sighting that year by businessman pilot Kenneth Arnold, and ends in 1969, with the termination of the U.S. Air Force's investigation, which existed for most of its duration as "Project Blue Book." The investigators ranged from kids with saucer clubs to serious-minded individuals with connections in government.
