Travel Air's 1926 Model 5000 combined airliner and racer roles with a single engine, 15.7-metre wingspan, and 9.3-metre fuselage. Reaching 197.9 km/h, this American aircraft served multiple purposes—scheduled passenger routes and competitive racing—reflecting the efficient, multi-role design philosophy of 1920s commercial aviation.
