In 1930 Thomas "Archie" Stewart, an early aviation enthusiast and descendant of prominent local dairy farmer Lachlan Stewart, convinced his uncle Samuel Stewart to donate "Stoney Lonesome", split between the towns of Newburgh and New Windsor, to the nearby city of Newburgh for use as an airport. In the early 1970s, Governor Nelson Rockefeller's administration saw the potential for Stewart Airport to support the metropolitan area. Its long runway made it particularly attractive for intercontinental service via supersonic transport, then under development in the U.S. and elsewhere. The Metropolitan Transportation Authority was the first government body to try to convert it into the New York metropolitan area's fourth major airport. It tripled the airport's territory, extending its land well beyond its previous western boundary at Drury Lane, a two-lane rural road. The state government used its eminent domain powers to take 7,500 acres for terminals, runways and a buffer zone expanding the airport from Newburgh into neighboring towns of Montgomery and a small portion of Hamptonburgh. The land was bounded by I-84 to the north, Route 207 along the south and roughly by Rock Tavern and Maybrook in the west.
