Production. B-25 bombers. Workmen at a Western aircraft plant perform finishing operation on a front section of a B-25 bomber. General Doolittle, who flew in a B-25 in the raid on Tokyo, has called the ship the best military plane in existence. With plenty of speed, a 1700-mile cruising range and a ceiling of 25,000 feet, it has performed brilliantly as a medium bomber and as an escort plane. Fairfax bomber plant, Kansas City
