Like most computer geeks I have flown flight simulators since pretty much the beginning of their existence. I started on the TRS80 and Apple and as soon as I went IBM, I switched to MSFS which is now the God of FS. I did not really get heavily into it tho until MSFS 2000 when the graphical aspect took a huge leap forward - and even then there was a reason that I ended up getting serious about FS'ing: The Boeing 377 Stratocruiser.

For an in depth description of what made this plane nirvana for me you can read my article on it (see links to the right) but to basically until June of 81 I had never even heard of this plane before. Until that is in 1981 I had the opportunity to take a ride in one of the last C97-B377 Hybrid Transports in existence with an approved flight certification. That ride is a story in itself but let me just say that after taking that ride I was hooked!

So my Flight Sim Page is dedicated to the Boeing B377 Stratocruiser!

About the B377

You might be tempted to look at the Boeing 377 as just another old and obsolete prop-liner but if you did, you would be wrong. The Model 377 Stratocruiser pioneered aspects of commercial airliner design that are still with us today. In fact without the Stratocruiser the Space Shuttle would not be what it is! Sound far-fetched? Read on...

The 377 was the first successful transcontinental airliner to see commercial service following World War II, though the Comet often is given credit for that. If you look close at the 377 you might just notice that it had a part in World War II in an odd way - it is constructed from modified hulls of bombers from the war! In fact its design incorporates TWO bomber bodies, the bottom hull cut lengthwise with another hull added on top of it to create the multi-deck body that is the 377. Early models actually have the blank faced gun mount in the front on the bottom that was later converted to hold the radar dish.

Modern airliners such as the Boeing 747 owe much to the 377 - from a dedicated lounge to sleeping berths that can now be found on the new Airbus models, the 377 has been there and done that a century ago! The first 377 was delivered in 1949 and the class stayed in service until 1960 when it was made obsolete by the Boeing 707 Jet Airliner. Still useful, the 377 stayed in service until the 1970's in the Third World, and although only 56 of the airliners were ever built there are still models in airworthy condition today.

The Space Shuttle owes a lot to the 377 - the special service and support planes called Guppies are actually built from Boeing 377's! In a play on the original design model, the top "hull" is removed and a much larger one is replaced to create a very large cargo hauling plane that is perfectly designed to move the modules that are built to be carried in the holds of the Space Shuttles. How is that for cool?

Just the Facts - The B377 List of Lists

(This is a work in Progress)

The history of the Boeing Model B-377 is not as clear as many of us in the FS community wish that it was and so I decided that if someone had to do it I may as well be the one... So I have set out to create the definitive guide to the entire run of the model, with notes as to the ultimate fate of each. This has turned out to be a major detective project as the data is not in any one place, so I have had to comb through the records of the manufacturer (Boeing) and the various Airlines and entities and as you can see from the list below there are still major gaps in the information.

As I am forced to only accept official records at face value, and while I appreciate the information that you all are sending to me about the various 377's, please be aware that unless I can verify the information from a minimum of three (3) seperate sources, I cannot accept it as valid. But fear not, significant progress is being made!

The B377 Model Types

Boeing 377-10-19: A single example was built and flown as the Stratocruiser prototype. It was sold to Pan Am in 1950 and brought up to 377-10-26 standard.

Boeing 377-10-26: These were the twenty ordered by Pan American. All were delivered with round passenger windows on both decks and a rear galley.

Boeing 377-10-26S: Refitted with larger engines and named Super Stratocruiser.

Boeing 377-10-28: Originally ordered by SAS, but taken up by BOAC, four in all. Like the Pan Am aircraft, they had round windows on both decks and a rear galley.

Boeing 377-10-29: Eight were built for American Overseas Airlines. These had round windows on the main deck, rectangular windows on the lower deck, and a rear galley. Shortly after entering service with AOA in 1949, the line was purchased by Pan Am, and these 8 aircraft finished their passenger carrying careers with Pan Am in 1960.

Boeing 377-10-30: Ten were built for Northwest. They were built with rectangular windows on the main deck and lower deck, and a rear galley. All were retired by Northwest in 1959.

Boeing 377-10-32: Six were built for BOAC. They had round windows on both decks, but a midships galley.

Boeing 377-10-34: Seven were built for United. These had rectangular windows on the main deck, round windows on the lower deck, and a midships galley. In 1954 the surviving United Stratocruiser fleet was sold to BOAC.

377F - Freighter Conversion.

Guppy Variants: Many and often modified. Going to need to research this more.
