One of the most storied aircraft of WWII, the Vought F4U-4 Corsair was the first single engine production aircraft capable of 400 mph in level flight. With its characteristic gull wing and giant 18-cylinder double wasp engine, it proved a superb fighter in the Pacific campaign and achieved victory ratio approaching 10 to 1. The exploits of the famed Black Sheep Squadron of Corsairs was recounted by their leader, Marine fighter ace Major Gregory "Pappy" Boyington, in the book "Baa Baa Black Sheep." The Handbook of Flight Operating Instructions told pilots everything they needed to know before climbing into the cockpit. Originally classified "Restricted", the manual was declassified long ago and is here reprinted in book form.
