Dr. C and Joseph D are thrilled to explore the origins of engine-powered flight! They catch up on work, Rob’s recent air travel, and jet lag. Then for the main topic, they start way back at the beginning of human flight using gliders and hot air balloons and talk all the way up to jet engine planes and boomerangs. In the after show, Joseph and Rob discuss other things that can or cannot fly and Joseph tells us what flying discs have to do with coffee.
