Pan Am ditched a 377 (aka. Boeing Trimotor)
There is/was a Boeing Trimotor, and a Boeing 377. Very, very different airplanes. Boeing Trimotor was pre-WWII and could be mistaken at quick glance for the better known Ford Trimotor.
Boeing 377 was based on the B-29 and had four engine (aka Stratocruiser).
