X-Plane 10.30 Consolidated B-24 Liberator. The Consolidated B24 Liberator was an American heavy bomber, designed by Consolidated Aircraft. Often compared with the better-known B-17 Flying Fortress, the B-24 was a more modern design with a higher top speed, greater range, and a heavier bomb load; it was also more difficult to fly, with heavy control forces and poor formation-flying characteristics. The B-24 ended World War II as the most produced heavy bomber in history. At over 18,400 units, half by Ford Motor Company, it still holds the distinction as the most-produced American military aircraft. By Larry Cole.
