For $1.5M, DeepFlight Dragon Is an "Aircraft for the Water" 76
Zothecula writes No one with red blood in their veins buys a sports car and hands the keys to a chauffeur, so one of the barriers to truly personal submarining has long been the need for a trained pilot, not to mention the massive logistics involved in transporting, garaging and launching the underwater craft ... until now. Pioneering underwater aviation company DeepFlight is set to show an entirely new type of personal submarine at the 2014 Monaco Yacht Show next week, launching the personal submarine era with a submersible that's reportedly so easy to pilot that it's likely to create a new niche in the tourism and rental market.

Going up from sea level to space (the maximum possible change in air pressure) is equivalent to surfacing from a depth of 10m. Coming up from a dive deeper than 10m is more dangerous, in terms of decompression sickness, than ascending in an unpressurised aircraft to any altitude.

It is designed aircraft-style with positive buoyancy. So you don't flood tanks or anything like that, you "fly" down using control planes to keep you down just as an aircraft uses wings to keep you up. So, just as an aircraft will descend to the ground if the whirly bits stop turning, so will this return to the surface.
