Military Spaceplanes Geek Out

What does the military want with a space plane? Time for a Geek Out! The conversation begins with that question - what space plane? Richard digs into the history of the space shuttle, which did have substantial funding from the US Air Force for specific military missions, none of which ever happened for a variety of reasons. And then off into the various projects to try and build a military space plane, including the DC-X, X-33, X-37B, DARPA RASCAL and the latest attempt, the DARPA XS-1. Each project brought some capabilities to the fore, but there's still a long way to go!
