  "My wife for Christmas one year got me a year of private lessons with Carlos Machado. ... I was in a situation where I had Armadillo Aerospace, my rocketry company at the time, we had enough space. So I had a whole bunch of mats set out there and I would work with Carlos and one of the other guys there on Saturdays."
