Since the beginning of humankind, we've looked to the sky and envied the flight of birds. Now, since the explosion of air travel, we dare to push the boundaries of science, going faster, farther and with bigger cargo. The C5 Galaxy is nicknamed the 'Screaming giant' for a good reason. What makes this plane's earth-shattering flight even possible with massive loads? The Airbus Tanker Craft has revolutionized flight, effectively infinitely extending the range and reach of military jets with unprecedented refueling capabilities. How do you safely refuel not one but two fighters midair at thousands of meters altitude? But planes aren't the only flying machine called upon to carry heavy loads great distances. When we peek under the hood of the CH53K Stallion King, we learn how engineering new rotor technology allows this beast to deliver a full Humvee and personnel anywhere! And, just when we think Zeppelins are a thing of the past, the Airlander 10 shows us how new composites and tech married to legacy form could be the way of the future of flight.
