Key Takeaways:

In the immediate post-WWII era, Boeing designed the 417 in 1946 as a twin-engine regional airliner intended to carry 20-24 passengers for shorter routes.
The 417 featured innovative design concepts for quick ground turnarounds and impressive short-field performance, which Boeing actively promoted through media and advertising, even securing an early order.
Despite its forward-thinking design and strong marketing, the Boeing 417, along with similar concepts from other manufacturers, never progressed beyond the drawing board due to the market being saturated with abundant and much cheaper surplus wartime aircraft like the DC-3.

The years immediately following World War II were interesting ones with regard to aircraft development.

Americans were returning home, and they were bringing with them a desire to spend money on goods and services, as well as the capability to manufacture them. Most aircraft manufacturers took a bullish approach to the impending boost in the economy and wasted no time designing new aircraft. Their designs ranged from small single-engine GA aircraft like the Navion to large transports like the Boeing 417, seen here.
