Colorized 1931 photo of a Curtiss B-2 "Condor" of the 11th Bombardment Squadron in flight over the Grand Canyon. From National Archives. It had a twin set of rudders with twin horizontal stabilizers. The B-2 was quickly made obsolete by technological advances of the 1930s, and served only briefly with the Army Air Corps, being removed from service by 1934.
