Long-Range Double Decker: 73 Years Of The Boeing 377 Stratocruiser

Date:

Boeing has designed numerous revolutionary aircraft over the decades, a pattern that the company can trace back to its early days. As the company continued its dominance in the United States aviation industry during the mid-20th century, it launched the 377 Stratocruiser, which was first delivered 73 years ago today.

Based on a legend

The B-29 Bomber was one of the most technologically advanced aircraft during World War II, with a total of 2,766 units being built before production ended in 1946. The success of the plane inspired new models after the war ended. One aircraft that was based on the famous military plane was the 377 Stratocruiser.

Boeing’s preceding major commercial aircraft, the 307 Stratoliner first flew before WWII began. Thus, it was time for a new solution.

The Stratocruiser performed its maiden flight on July 8th, 1947, and impressed potential customers with its pressurized cabin that came with two passenger decks. It was larger than rivals such as the Lockheed Constellation and Douglas DC-6. However, it was more expensive and less reliable.

On board comfort

Nonetheless, despite the drawbacks, the aircraft drew significant attention from some key players and catalyzed the evolution of commercial aviation. Pan American placed the first order for the type, with 20 units on the books.

Pan Am first took delivery on January 31st, 1949, and introduced the aircraft on April 1st that year. The legacy carrier inaugurated service with aircraft between San Francisco and Honolulu.

Pan Am’s passengers would have enjoyed the spacious setting and luxurious decor in the cabin. The aircraft was great for overnight trips across the US due to its comfort.

“The Stratocruiser set a new standard for luxurious air travel with its tastefully decorated extra-wide passenger cabin and gold-appointed dressing rooms. A circular staircase led to a lower deck beverage lounge, and flight attendants prepared hot meals for 50 to 100 people in a state-of-the-art galley. As a sleeper, the Stratocruiser was equipped with 28 upper-and-lower bunk units.”  – Boeing stated.

End of the run

Amid the ever-changing requirements of the aviation industry, including the arrival of the jet age, the Stratocruiser found it hard to keep up with the civil transitions. It also suffered 13 hull-loss incidents and caused 139 fatalities in the space of 19 years. Subsequently, the aircraft began being adapted and phased out.

“During the early 1960s, Aero Spacelines ballooned the Stratocruiser’s fuselage into a whale-like shape to carry spacecraft sections. Nine of the variants were assembled. The first was called the Pregnant Guppy, followed by five larger Super Guppies and three smaller Mini Guppies.” – Boeing added.

Altogether, 65 units of the Stratocruiser were produced between 1957 and 1950. The aircraft saw action from national and global carriers, including Línea Internacional Aérea, BOAC, the Israeli Air Force, AOA, Nigeria Airways, United Airlines, and Rutas Aéreas Nacionales SA. Boeing fondly remembers the type for it bringing the company its first considerable success in the international market.
