The Condor II biplane was a Curtiss-Wright model designed for varied transport. "155" may refer to its cruising speed. Models of the Condor II biplane include BT-32 (for bomber transport), AT-32 (air transport), and CT-32 (cargo transport). Some models of the Condor II offered convertible sleeping compartments and were used by the forerunners of both American Airlines and Eastern Airlines. Condor II aircraft were also part of some civilian and military fleets in the United Kingdom and China. Admiral Richard E. Byrd used a specially equipped model in his 1933 Antarctic expedition.
