Avrocar; Canada's Flying Saucer; The Story of Avro Canada's Secret Projects [signed] [first edition]

Designed for use by the U.S. military, these flying saucers were developed by Avro Canada's Special Projects Group between 1952 and 1962. (Two survive in U.S. museums.) This wonderful book shows flying saucers in various stages of production and in actual test flights. U.S. military illustrations show the saucers' potential use in combat.
