The Boeing 377 Stratocruiser is a large, four-engine commercial aircraft developed in the late 1940s. It was designed for long-distance travel and could carry up to 100 passengers. The Stratocruiser featured a spacious cabin and was known for its luxurious amenities, making it popular among wealthy travelers. First flown in 1947, the Stratocruiser was based on the military Boeing C-97 Stratofreighter. It had a distinctive double-deck design, which allowed for a unique passenger experience. Although it was retired from commercial service by the 1960s, the Stratocruiser remains an iconic symbol of early post-war aviation.
