Project Silver Bug
By December 1954, with the USAF Scientific Advisory Board studying the Avro concepts, Project Blue Book acknowledging their existence and Air Research and Development Command funding their development to the tune of several million dollars, the saucers were apparently achieving a fearsome reputation in certain quarters within the Air Force. Air Intelligence Digest issued a somewhat credulous article on the possible existence of Soviet saucers. Frost's theory that the Soviets might be launching their saucers from submarines reached its highest expresion here.
