VANISHINGS: The Abandoned Airship

For a dozen turbulent years between the two World Wars, the United States Navy poured millions of Depression-era dollars into an audacious dream: to rule the skies with a fleet of massive airships. Armed with their own squadrons of scout planes, these "Battleships of the Skies" could travel far over the horizon to detect the enemy's approach. Journey into a lost chapter of military history to discover how the airships USS Shenandoah, USS Akron and USS Macon were lost in a series of terrible aviation disasters that shocked the nation and altered the evolution of aerial warfare.
