Boeing 247
American twin‑engined airliner introduced in 1933 that set new standards for speed, safety and passenger comfort through all‑metal construction and advanced systems.
Overview
The Boeing 247 was a pioneering American airliner that entered service in the early 1930s. Widely regarded as one of the first modern airliners, it combined an all‑metal monoplane layout with aerodynamic refinements and systems that were advanced for its time. The airplane helped establish new expectations for speed, reliability and onboard comfort in scheduled airline service. Historical summaries often cite the 247 as a turning point between the biplane era and the streamlined transports that dominated later decades.

Design and key features
The 247 introduced several features that became standard on later transports. Its basic configuration emphasized efficiency, safety and passenger convenience. Notable characteristics included:
- All‑metal, stressed‑skin construction: a stronger, smoother airframe than typical wood‑and‑fabric designs of earlier years.
- Retractable landing gear: reduced drag compared with fixed gear and improved cruise performance; an early example of this on an airliner was a selling point for operators.
- Advanced systems: provisions such as pneumatic de‑icing boots and an automatic pilot helped maintain operations in adverse weather.
- Passenger amenities: a comfortable, enclosed cabin laid out for a small group of passengers with attention to noise and vibration reduction relative to earlier types.
Development and operational history
The prototype made its first flight in February 1933 and the type entered scheduled airline service later that year. Built by Boeing for use in mainstream airline operations, the 247 served on primary routes and demonstrated that fast, reliable, and relatively quiet air travel could be a practical commercial product. Dozens of examples were produced and operated by major carriers of the period; some airframes also served in military or corporate roles as needs evolved.
Impact, legacy and successors
Although larger, longer‑range and pressurized designs followed before World War II, the 247 influenced subsequent airliner design by normalizing features that are now commonplace. Its blend of systems, structure and operational capability anticipated developments such as pressurization and multi‑engine long‑distance transports. The Boeing 307 Stratoliner, which introduced cabin pressurization to airliners, built on the developmental lineage to which the 247 contributed. See related developments.
Notable facts and distinctions
The Boeing 247 is frequently mentioned in discussions of aviation milestones because it combined multiple advanced features in a single, commercially successful package. While later aircraft increased capacity and range, the 247 remains a reference point for the shift toward modern passenger transports.
