Book excerpt: The epitome of grace, beauty and design, the Supermarine Spitfire was one of the most deadly fighters of WWII. The Spitfire prototype, designed by Supermarine¿s Chief Designer R.J. Mitchell, first flew in 1936. By the time the Battle of Britain began in earnest, nineteen Spitfire squadrons were available to the RAF. Their pilots were most often tasked with engaging Luftwaffe fighters, including the Bf-109. With its superior maneuverability, it proved more than a match. This pilot¿s flight operating handbook, for the Model IIa and IIb, was originally produced by the Royal Air Force during World War II. It has been slightly reformatted but is reproduced in its entirety. It provides a fascinating view inside the cockpit of one of history¿s great planes.
