Modern Marvels S09E15 Ball Turret Gunners

Fast-paced, fun and informative, Modern Marvels is The History Channel's signature series focusing on historical technology. The series has focused (among other things) on wonders of construction (Erie Canal, the Pentagon, the Chesapeake Bay Bridge, the Big Dig), the machinery of war (nuclear submarines, tanks) as well as technology linked to the everyday (power tools, home tech, garbage).
