Rocketman Blog interviews Armadillo's John Carmack on the X-Prize Race
Nice interview covering Carmack's approach and progress. Interestingly, for their Black Armadillo contender they use H2O2 monopropellant fed to 4 slightly canted engines, sophisticatedly computer controlled by John-boy's software. Lands nose first on a crushable nosecone, which is replaced for the next flight. Remarkable progress from a smart, hard working buncha guys just working part time. Best o' luck, people!
