I found this interesting clip of a SEAmagine launch. I'm interested in if they vacuum the air out of the inflatable pontoons. Also notice that they are using a SCUBA type small pressure gage outside the sub. This is what I've been thinking about doing as well. I didn't realize that a Ocean Sun fish swam like that. Pretty amazing stuff. Frank we will have to find that spot and dive there, with or with out a metal cocoon. http://www.youtube.com/watch?v=bCYvZWB7wkI&feature=related Szybowski |
