Yeah, that is some fun stuff. I really liked the back-facing camera, but sadly it got partly covered during the flight.
I think launching that baby is really expensive (apart from all that Aluminium, GFK and Electronics for the bare body). It gives you some really cool video footage and it somehow reminds me of the Toshiba HD-TV with the chair and weather balloon....hehe
They seemed to take care of a lot. I just saw a video on Youtube last weekend where somebody shot his homebrew Pershing (Aluminium with Wood Parts) up. Looked really cool until it crashed down several hundret meters ago.....no parachute
At least you have a lot of paperwork with the government I think.
