How many people could fit in a World War 1 airplane?

World War I airplanes typically had a limited capacity, generally accommodating one to two people. Most fighter planes, like the Sopwith Camel or the Fokker Dr.I, were designed for a single pilot, while some reconnaissance or bomber aircraft could carry a pilot and an observer, totaling two people. The cramped cockpit space and the design of these aircraft prioritized maneuverability and performance over passenger capacity.
