The Boeing 377 Stratocruiser was a large, long‑range airliner derived from the C‑97 Stratofreighter, itself a B‑29 Superfortress variant. It first flew on 8 July 1947 and featured a double‑deck, pressurized cabin that could seat up to 100 passengers on the main deck and 14 in a lower lounge. The aircraft was designed for premium transoceanic service and was one of the first commercial planes to use a double‑decker layout.
