James Cameron Returns from Deepest Spot on Earth

LINK - WOW would I love to be this guy. This is something I intend on doing someday, when I become wealthy (:D). I have always dreamed of exploring the oceans and building submersibles. The oceans are a really unexplored environment. From what I understand, we don't know the geography of the entire ocean landscape. We know where the major continental faults and trenches and so forth are, but in terms of all the geography, I think much of that is unknown at the moment. We also have only a fraction of understanding of the myriad lifeforms that live in the ocean. So there is much work to be done in terms of oceanographic exploration.
     When you think about it, Earth really is a water planet. To give an appreciation of the surface area covered by the oceans, if you add up the surface area of the Earth's continents, the surface area of the planet Mars, and the surface are of the Moon, you still do not reach the surface area covered by the oceans. That's a LOT of space to explore!
     It's rather comical to think about how arrogant humans used to be regarding the oceans. It used to be believed that the continents were fixed in place and did not move, that no lifeforms whatsoever existed on the bottom of the ocean, and that the entire ocean landscape was just barren and flat, basically an underwater desert. Then when scientists actually began going under the ocean and exploring, they found (in what shouldn't have been shocking), that the ocean actually has loads of mountains, ridges, ravines, you name it, along with lots and lots of lifeforms.
     Cameron himself has done dozens of ocean dives and is friends with most all the people active in the underwater exploration community. I would hope to someday become one of these people, but it will require some money. It would be great though to just have a big yacht (for this, an expedition yacht, which is a rugged yacht meant for exploration) with a submersible attached to it that one could use for deep ocean exploration.
     Graham Hawkes, the founder of Deepflight Sumbersibles, has been working for years to create what are essentially underwater aircraft. These are submersibles that would operate independently of any mother ship. You just put them into the water and "fly" underneath (they stay underwater using the opposite process of how airplanes use their wings to stay in the air). The benefit of such a craft is that if you stop underwater, you just float back to the surface (so no fear of being trapped if you broke down underwater). The downside however is that in order to stay submerged, you must be moving forward. Most current submersibles operate like underwater blimps and require a mother ship on the surface for support.
     It would be very awesome I think to get one of these craft and drive it underwater in say the tropics (clear blue water) and have a clear view of all sorts of different underwater lifeforms. Last I heard, the engineering challenge is how to get these craft to go deeper than 2,000 feet (I think Graham had said they have a "floor" of about 2,000 feet). Maybe they have since then surpassed that, I am not sure. These craft however cost some serious money as well.
