A gritty, true-life series exposing the world of history's most notorious and dangerous gangs.

Assault from the air didn't begin with the era of the airplane. Take a look back at early methods of airborne attack. The kite bomb was a medieval siege weapon that dropped bombs from a kite over cities. We'll build one and test it with startling new insights and success. Ancient bouncing bombs that actually skipped across water--the forerunners of the famous Dam Buster projectiles--terrorized shipping in Turkey in 1453. Learn the secrets of ancient China's whistling arrows--used by commanders to direct the flow of a battle. Investigate the world's earliest rocket-powered explosive missile from the ancient battlefields of China. Finally, in one of the most dramatic tests ever conducted, we'll build the earliest known successful parachute and drops a skydiver from 6,000 feet.

Lurking beneath Lake Nemi's blue waters lay the titans of Roman naval engineering--the Nemi Ships. Titanic luxury liners of the ancient world, they held inventions lost for thousands of years. But why were they built? Were they Caligula's notorious floating pleasure palaces--rife with excess and debauchery? Flagships of a giant sea force? It took Mussolini's obsession with all things Roman to finally prise the two wrecks from the depths of Lake Nemi near Rome. Using an ancient Roman waterway, he drained the lake and rescued the ships, an accomplishment captured on film that we access to illustrate this astounding story. Sophisticated ancient technology discovered in the boats transformed the understanding of Roman engineering overnight. Yet by 1944, the adventure had turned sour and the retreating German army torched the boats. We reveal the mysteries of the Nemi Ships and the ancient technology that made them possible.
