Either this is nothing special or I just hang around a weird crowd. I know a some guys that made three submarines, and they go to 1500 feet. The biggest one is the largest amateur submarine in the world. See pictures here: http://www.submarines.dk/ http://www.submarines.dk/ They are currently working on commercial spaceflight: The goal is to make a rocket that will get one person suborbital but weightless and back down. They expect to do it within a couple of years. They just had their first public motor test, you can see a clip here: http://ekstrabladet.dk/nationentv/klip/?clipid=17454&clipfra=1 http://ekstrabladet.dk/nationentv/klip/?clipid=17454&cli... . (links are in Danish) And they're just a couple of guys with no money to speak off, but they are crazy and they believe they can do it. So do I.
