What characteristic distinguishes the Boeing 747-8 from previous 747 models?

The Boeing 747-8 is distinctly recognized for its longer fuselage when compared to previous models in the 747 series. This increase in length not only contributes to its status as the longest commercial aircraft in the world but also allows for a greater seating capacity and increased cargo space. The design modifications, including the stretched fuselage, were pivotal in accommodating more passengers and adapting to modern airline needs while maintaining the aircraft's iconic humpbacked appearance. This feature sets the 747-8 apart from earlier iterations, showcasing Boeing's commitment to progressing aviation technology and responding to market demand for efficiency and higher capacity.
