The Boeing 377, sometimes called the Stratocruiser, was an airliner made by Boeing after World War II. It was made from the C-97 Stratofreighter, which was a type of Boeing B-29 Superfortress used to move troops around. The Stratocruiser first took off on July 8, 1947.
Design and development
The Boeing 377 used the bottom and the wings of the B-50 Superfortress. The 377 was bigger than the Lockheed Constellation and Douglas DC-6 and it could fly for longer. Boeing stopped making the 377 in 1950.
Pressurization (first used on the Boeing 307) meant that if the plane was flying at 15,500 ft (4,700 m), to the passengers it would be like they were on the ground.
56 Stratocruisers were made. 55 of these were made for airlines.
Different types of Boeing 377
- Prototype. It was given to Pan American World Airways in 1950.
- 20 given to Pan American World Airways.
- 10 aircraft with better engines and more fuel. It was called the "Super Stratocruiser".
Many other types were made, but most of them only had changes made to the shape of the windows.

The Stratocruiser had 13 hull-loss accidents between 1951 and 1970. A hull-loss accident is when a plane is damaged so badly it cannot be fixed. 140 people died in these. The worst accident happened on April 29, 1952.
