When Ann and I were visiting with Bob in York, Maine, he shared a photo of him and Heck Bardsley next to NASA Astronaut Chris Cassidy, who is floating far above us in the International Space Station right now (see the whole crew here).
My theory is that NASA uses jeeps with stock brakes for physiological tests. If an astronaut can stop a vintage jeep going 60mph with stock brakes, they can handle just about anything! Chris won’t get to ride in another jeep until he and his crew land in September, 2013. (And I thought our eight week trip was long!)
