Douglas A-20 Havoc Pilot's Flight Operating Instructions

Book excerpt: Designed by Douglas Aviation engineer Ed Heinemann, the A-20 Havoc and its variants served in the U.S. Army Air Force and those of several allies. The plane was configured for attack, night fighter, and bomber roles, and nearly 7,500 were built from 1939 through 1944. The first order for the Havoc came from the French, who extensively tested the prototype aircraft after the USAAF failed to place an order. The French insisted on modifications that included new 1000 hp Pratt & Whitney engines (later upgraded to 1100 hp) and a narrower fuselage. The improved A-20¿s speed and handling compared favorably to a fighter aircraft. Little wonder it became one of the most extensively-built light bombers of WWII. Originally printed by the U.S. Army Air Force and Douglas, this handbook provides a fascinating glimpse inside the cockpit of this warbird. Originally classified ¿Restricted¿, the manual was declassified and is here reprinted in book form.
