what is it?
The Douglas B-18 Bolo is an American twin-engined medium bomber which served with the United States Army Air Corps and the Royal Canadian Air Force (as the Digby) during the late 1930s and early 1940s. The Bolo was developed by the Douglas Aircraft Company from their DC-2 as a replacement for the Martin B-10. By 1940 standards, it was slow, had an inadequate defensive armament, and carried too small a bomb load.
How to recognise it: 2 piston engines with propellers · mid-wing aircraft · retractable tailwheel (taildragger) · 27.3 m wingspan
