A triplane is an aircraft design featuring three stacked wings, which provides increased lift and improved maneuverability compared to traditional biplanes or monoplanes. This configuration allows for a more compact wing structure, enhancing the aircraft's performance, especially at lower speeds. Triplanes were notably used during World War I, with famous models like the Fokker Dr.I becoming iconic for their agility in dogfights. While their popularity declined with advancements in aviation technology, triplanes remain a significant part of aviation history and are often celebrated in airshows and vintage aircraft exhibitions.
