1980s, Port Washington's sandbanks were a major industrial center: the Port Washington Public Library's \"Sand and City\" archive describes a workforce of immigrant sandminers and scow captains who \"transported raw materials to New York City and beyond,\" drawing workers from Italy, Ireland, Germany, Nova Scotia, Poland, Norway and Russia.[9][10] The Cow Neck Peninsula Historical Society states that, \"by some calculations, 90% of the concrete that built the sidewalks, the skyscrapers, the subway tunnels, [and] the building foundations of NYC came from\" Port Washington sand, more than 100 million tons of it shipped by barge to Manhattan.[10]", "In the late 1930s Port Washington's harbor was a base for transatlantic flying-boat travel. On July 9, 1937, piloted by Captain Harold E. Gray, a Pan American Sikorsky S-42B Clipper departed Port Washington and reached Foynes, Ireland, the first commercial survey flight across the North Atlantic; an Imperial Airways flying boat, the Caledonia, arrived at Port Washington from Foynes on the same date. A plaque commemorating the flights was erected at the Town Dock by the Wings Club in 1969.[6] Two years later, Pan American's Dixie Clipper — a Boeing B-314 captained by R. O. D.
