Raised on the rugged plains of Australia, Matt Wright had plenty of jobs -- horse wrangler, Australian Army soldier, crocodile egg collector -- that helped develop his passion and skills for a career as a helicopter pilot and wildlife relocator. Featured in half-hour episodes of "Outback Wrangler," Wright tracks down, captures, and transports a diverse range of dangerous animals, including crocodiles, wild buffalo and even polar bears, that are posing a threat to people. As a chopper pilot he is able to access areas that would otherwise be impossible to reach. Matt's goal, he says, is based on the preservation of wildlife: to remove and relocate problem animals rather than kill them.

The brain waves of a pilot are documented as he attempts to land an aircraft in crosswinds, and engineers are seen working on an Airbus A380's engine. Other episodes include the operations behind movement of luggage, how the conveyor belt system works and how controllers can single out pieces of luggage among thousands.
