This new book chronicles not only the aptly named P-61 "Black Widow", but also the Douglas P-70 series, the P-38 night fighter variants, the Bristol Beaufighter, B-25s and the DeHavilland Mosquito - the proposed XA-26A and the P-39 nightfighters are also discussed. Historical accounts of American night fighter pilots, as well as the complete history of all night fighter squadrons formed during World War II are included, as is the development of radar and modern air defenses. This book is the product of over twenty years of study and research. Its sources include the National Archives, Northrop Aircraft archived, the U.S. Air Force Museum, the Imperial War Museum, the Smithsonian Air & Space Museum and interviews with P-61 test pilots, designers and engineers. Garry Pape's previous works include books on the P-61 and the P-38 night-fighter versions. He is currently employed by Northrop, after years with Hughes and Lockheed, and lives in California. Brig. Gen. Ronald Harrison is an F-16 Wing Commander in the Air Force Reserves, and lives in Georgia as an attorney.
