8. RAF Hethel: England
Another joint effort between the United States and England, the U.S. Army built—what they later named RAF Hethel—near Norfolk, England in 1942. It was both an airfield and a place to house displaced military families during the war. For years after the war, some 900 displaced Polish families lived in the Nissen hut buildings on the land. The Polish camp closed in 1960, but not before they buried a number of the Polish inhabitants in a graveyard on the property. Today, the Lotus car company has a factory on the site of the former airfield.
