"Dangerous Flights" goes inside the perilous business of aircraft delivery, following six pilots as they risk their lives to deliver small, used airplanes to destinations around the world. The business takes them from the frozen Siberian arctic to the Amazon rainforest, often through unpredictable situations and life-threatening weather conditions. Each episode features different "ferry-flying" missions, as the pilots battle co-workers, demanding customers and the elements in order to deliver the airplanes intact and on time.

You might say the Tweto family business has taken off, despite the sometimes unforgiving conditions in which it operates. The Twetos -- dad Jim, mom Ferno, and daughters Ariel and Ayla -- run Era Alaska, an airline that transports life's necessities to the isolated rural inhabitants of the Bering Sea coastline. Whether it's carrying sled dogs bound for the Iditarod race, medicine for sick children or food supplies to miners working on the North Slope, the Era Alaska crew serves as a lifeline for many of the state's residents.

A fearless guy apprentices himself to people who perform dangerous or disgusting jobs, ranging from rattlesnake catcher and zoo cleaner to road-kill collector.

The breathtaking beauty of Alaska sometimes hides the fact its winters can be incredibly harsh, especially for those who live in the state's outlying areas. "Alaska: The Last Frontier" perfectly illustrates this reality, as the series profiles life for the Kilcher family in the isolated community of Homer. For four generations the Kilchers have lived off what their 600-acre homestead has provided, but cultivating that living is never easy. Led by patriarch Atz Kilcher and his brother Otto, the family spends the short summer and fall gardening, hunting and fishing for food, gathering supplies from the land and preparing their animals for the winter. Viewers, who may or may not have a fancy phone by their side while watching on their big-screen high-def TV, also see the Kilchers living off the grid, where running water and electricity aren't daily staples, nor is contact with the outside world. Atz, by the way, is the father of music superstar Jewel.

The gold rush in Alaska isn't confined to the state's precious ground. It's taking place on the sea ... or more accurately, on the bottom of the frigid Bering Sea. This series, from the creators of the Emmy-winning "Deadliest Catch," follows four gold dredges and their eccentric and driven crews who risk their lives to find as much gold as possible before winter sets in and it's too dangerous to dive. The custom-built rigs, some barely seaworthy, include an 80-foot barge run by the most successful gold dredger in Nome, Alaska, and a modified skiff that seats only two people.

Patrolling America's largest state is the job of roughly 400 troopers in one of the toughest law enforcement agencies in the nation. Essentially, these cops say, nearly every Alaskan resident is armed and they know how to use their weapons, which makes any scenario a trooper encounters a potentially fatal one. Follow along as the "blue shirt" Alaskan State Troopers police the towns and villages, and the "brown shirt" Alaska Wildlife Troopers enforce regulations covering both commercial and sport fishing and hunting activities.

According to a legend that dates back to the 16th century, a cache of Incan gold worth hundreds of millions of dollars is hidden off the coast of southeastern Brazil. It's known as the "Treasure of the Trinity," and it's eluded all who have sought it for 500 years. But a modern-day team of explorers follows a radical new theory to uncover its whereabouts: a remote, treacherous island where thousands of deadly vipers roam. Cork Graham leads the expedition to Queimada Grande -- known to locals as Snake Island -- armed with advanced technology to unearth complex clues and decipher puzzles that have protected the treasure for centuries. This Discovery series takes viewers along on the epic journey to one of the most dangerous places on Earth.
