Balzer. This volume examines the Ascender XP-55, Curtiss' unconventional answer to the U.S. Army Air Corps' call for aircraft with improved performance, armament, and pilot visibility over existing fighters in 1940. An unusual design for the time, the XP-55 had a canard configuration, a rear-mounted engine, swept wings, and two vertical tails. You'll learn about that prototype, nicknamed the "Ass-ender," from its earliest development to its final flight tests. 72 pages, B&W photographs, 8¼"x 10¾", softcover.
