Originally Capital Landing Field, the airport opened in mid-1930 and was Harrisburg's first airline airport. In 1934 the Commonwealth of Pennsylvania purchased it and renamed it Harrisburg-York State Airport. It was a stop on longer air routes, principally between Pittsburgh and Philadelphia. The airline was Transcontinental and Western Airlines which became TWA and remained until 1968. (DC-9s replaced TWA's last Constellations in 1967; the 4970-ft runway was one of the shortest in the country to see airline jets.) Allegheny and Capital/United appeared in the 1940s; United pulled out in 1966.
