WASHINGTON (AP) -- Houston s Astrodome stadium, New York s old Pan Am Worldport Terminal at Kennedy Airport and Montana s one-room schoolhouses are joining a list of the nation s most endangered historic places.

On Wednesday, the National Trust for Historic Preservation released its listing of America s 11 Most Endangered Historic Places. It includes sites from Maine to Alaska.

The Astrodome was the world s first domed, air-conditioned stadium and was once called the eighth wonder of the world. On Wednesday, a county board recommended converting the Astrodome into a giant convention center and exhibition space.

At New York s JFK Airport, the flying-saucer-shaped Worldport Terminal helped usher in the jet age in 1960 but has been vacated by Delta Air Lines and faces demolition.
