Seattle-Tacoma International Airport, one of the busiest air terminals of the U.S.A. Seen loading on right the tall tail of a Pan-American 707 Jetliner, on the landing strip a Trans-Canada DC3, the old workhorse, and to the left a conventional Western Airlines plane. What a contrast between the old and new in passenger aviation! Color photo by Max R. Jensen. Circa 1960′s.
