On a July afternoon in 1937, 15-year-old Betty Klenck Brown was listening to her family's shortwave radio. She was writing down lyrics to popular songs when she turned the dial and heard the unimaginable: "This is Amelia Earhart. This is Amelia Earhart." Betty jotted down everything she heard over 3 hours. Also in the show: A look at the restaurant of the stars, Le Cirque.
