episode description
The Hindenburg wasn’t the only air ship to end in a catastrophic crash. In 1935, the USS Macon went down in 1000 feet of water off the coast of the Western United States. Now, as scientists study the recently-discovered wreckage, new and improved dirigibles are returning to rule the skies once again. It's not James Bond - it's Graham Hawkes, record holder for the deepest underwater solo dive and inventor of Deep Flight, a winged submersible that may revolutionize underwater travel. Find out what makes this unique machine “fly” underwater. Sailboats have been sailing the world’s oceans for hundreds of years. But despite their rich heritage, scientists and boat designers continue to learn more each day about what makes a sailboat move. Contrary to what you might expect, the physics of sailing still present some mysteries to modern sailors.
