Bellanca 77-140

The Bellanca 77-140 Bomber was a twin-engine bomber built in small numbers in the United States in the 1930s. It was derived from Bellanca's Aircruiser civil transport, with the Aircruiser's single nose-mounted engine replaced by two Wright R-1820 engines of 650 horsepower each on the upper wing. The crew was two, a pilot and a gunner, and the armament was two .30 caliber machine guns in an open nose turret with up to 2,200 pounds of bombs. It spanned 77 feet, had a gross weight of 12,250 pounds and a maximum speed of 180 mph. The United States military was not interested in the type, but the Colombian Air Force bought a small number, including a float-equipped version called the 77-320 Junior, which differed from the landplane in having a fully enclosed nose turret.
