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。

A Revolution in Civil Aviation
这 波音307型斯特拉托利纳 was a milestone in aviation history. Introduced in 1938, it was the first commercial transport aircraft to feature a pressurized cabin. This allowed the Stratoliner to fly at 20,000 feet, far above the turbulent weather that plagued earlier airliners like the DC-3. By utilizing the wings, tail, and engines of the B-17 Flying Fortress, Boeing created a robust, high-altitude cruiser that changed the definition of luxury and speed in the “Golden Age” of flight.

Engineering the High-Altitude Cabin
- Circular Fuselage: Unlike the flat-sided aircraft of the era, the 307 featured a perfectly circular cross-section. This shape was necessary to evenly distribute the internal pressure stresses required to maintain a breathable atmosphere at high altitudes.
- Pressurization System: The Stratoliner used engine-driven superchargers to pump air into the cabin. This allowed passengers to enjoy an “8,000-foot” environment while the aircraft cruised at 20,000 feet, effectively avoiding the “bumps” of low-level air.
- B-17 DNA: To save on development costs and improve reliability, Boeing used the flight surfaces of the B-17C Flying Fortress. The wings, landing gear, and horizontal stabilizers were nearly identical to the bomber, giving the 307 legendary structural strength.
- Sleeper Comfort: The wide fuselage allowed for reclining seats and berths, making it one of the first true “sleeper” transports for transcontinental travel.
The “C-75” and Notable History
- Military Service (C-75): During WWII, the five Stratoliners operated by TWA were pressed into service for the Army Air Transport Command. Designated as C-75s, they were used for high-priority transatlantic flights because their pressurization allowed them to fly above most interception threats.
- Howard Hughes and the “Flying Penthouse”: The famous billionaire bought a Stratoliner and converted it into a lavish private office and home. After being damaged in a hurricane, the fuselage was eventually converted into a “Cosmic Muffin” house boat.
- Rare Survival: Only 10 Stratoliners were ever built. The only surviving example, the “Flying Cloud” (formerly of Pan Am), was meticulously restored by Boeing volunteers and is now at the Steven F. Udvar-Hazy Center.
