The National Trust for Historic Preservation has released its 2013 list of 11 Most Endangered Historic Places and the Worldport Terminal is on the list. The unique flying-saucer-shaped Worldport Terminal built by Pan Am in 1960 at New York’s Kennedy Airport was a symbol of the jet age. It’s where The Beatles first arrived in the U.S., along with millions of other travelers. But it’s become rundown and outdated, and asbestos abatement made renovations costly. Delta Air Lines recently abandoned the terminal for a new building, and demolition crews have already begun work on the futuristic structure from the past. (AP Photo/Mary Altaffer, File)
