The Ford Trimotor
5-AT was used by almost all the U.S. airlines. Introduced in 1928, these planes
could carry 14 or 15 passengers in its corrugated fuselage. It was produced
through 1932, but these planes stayed in use much longer. One Trimotor 5-AT,
built in 1929, was still being used in Las Vegas for sightseeing in 1991.
