The Busiest Airport Nobody Knew About

Deep in the mountains of Laos in a valley lies the busiest airport nobody knew about. Yet, at the height of the Vietnam War, it was home to 40,000 people and one of the busiest airports in the world. Welcome to Long Tieng. In this episode of Beyond the Borderline, we uncover the hidden history of the "Secret War". We explore how the CIA built a massive clandestine headquarters in the Laotian jungle, the tragic sacrifices of the Hmong army led by General Vang Pao, and what remains of this ghost city today. From the secret flights of Air America to the major battles on the plain of jars, this is the story of the city that history tried to forget.
