Here's a sleek and efficient early option for commercial aviation. The Russian Yakovlev Yak-40 is a three engine airliner that took its first flight in 1966 before going into production in 1967. They are low capacity, but provide a fantastically low cost and fast mode of aerial transportation from 1967 to 1981.
