| Nelson Ketch Wade, ME | Do a search on cosmic muffin, the name of the houseboat that was Howard Hughs plane, it has some more history on the plane. A few weeks ago I was in the Smithsonian and saw the 307 on display, It has to be the nicest looking plane ever built. 06/07/2007 @ 10:55 [ref: 16771] |

| The Boeing Company Chicago, IL | The Model 307 Stratoliner was the world’s first high-altitude commercial transport and the first four-engine airliner in scheduled domestic service. With names like Rainbow, Comet, Flying Cloud and Apache, the Stratoliner set new standards for speed and comfort.
Its pressurized cabin allowed the airplane to soar above rough weather at an altitude of 20,000 feet — higher than any other transport of its time. Its circular fuselage provided maximum space for the five crew members and 33 passengers. The nearly 12-foot-wide cabin had space for comfortable berths for overnight travelers. The Stratoliners attracted the attention of multimillionnaire Howard Hughes, who bought one for himself and transformed it into a “flying penthouse” with a master bedroom, two bathrooms, a galley, a bar and a large living room. Hughes sold it to a Texas oil millionnaire, and it ended its days as a palatial, Florida-based houseboat. The Stratoliner was the first airplane to have a flight engineer as a member of the crew. The engineer was responsible for maintaining power settings, pressurization and other subsystems, leaving the pilot free to concentrate on other aspects of flying the aircraft. Boeing built 10 Stratoliners. In 1940, the 307s started flying routes to Latin America and from New York to Los Angeles. Production stopped at the onset of war, and five were drafted into the Army Transport Command as C-75 military transports.
