这 波音307型斯特拉托利纳 是第一架使用加压机舱投入服务的商用运输机。这一功能使飞机能够在20，000英尺（6，000米）的高度巡航，远远高于许多天气干扰。压力差为 2.5 psi （17 kPa），因此在 14，700 英尺（4，480 米）时，机舱气压相当于 8，000 英尺（2，440 米）的高度。307型机载着6名乘客和33名乘客。除了民用服务外，美国陆军空军还将其作为波音C-75斯特拉托利纳飞机飞行，后者将其用作远程货运飞机。

这 波音307斯特拉托利纳 was the first commercial airliner to feature a pressurized cabin, allowing it to fly at higher altitudes and avoid bad weather. It was developed from the Boeing B-17 Flying Fortress bomber and entered service in 1938 with Pan American Airways. The 307 had a capacity of 33 passengers and a crew of five, and could fly at a maximum speed of 246 mph (396 km/h).
The 307 was also the first airliner to offer a flight engineer position, who monitored the four 莱特 R-1820 旋风分离器 radial engines and the cabin pressure. The 307 was a technological breakthrough in aviation history, but it faced competition from the Douglas DC-3 and DC-4, which were cheaper and more reliable. Only 10 307s were built, and none of them are in service today. The last surviving 307, named the Flying Cloud, is on display at the Smithsonian National Air and Space Museum in Washington, D.C.
