Key Takeaways:

In the post-WWII era, Boeing designed the 417, an innovative twin-engine regional airliner concept targeting 20-24 passengers.
The 417 featured advanced operational concepts aimed at achieving quick turnaround times, including self-sufficient boarding with airstairs and cargo handling designed to match truck beds, as well as simultaneous refueling and loading.
Despite Boeing's extensive marketing efforts, including ads and securing initial orders, the 417 never moved past the drawing board due to the overwhelming availability of inexpensive, surplus WWII aircraft like the DC-3, which offered better profitability for airlines.

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.
