When you count yourself amongst the worlds wealthiest people you can commission just about anything, and if you are British mogul Richard Branson that means an "underwater plane" named "Necker Nymph," that can dive up to 40 meters below the surface of the water. No matter how cool this thing is, you don't become one of the world's richest without finding some way to make money from your belongings. If you are so inclined you can charter the $631,000 flying sub for $25,000 and another $88,000 for the sub's superyacht launch vessel, "Necker Belle."
The Necker Nymph uses fighter jet technology and was designed by Hawkes Ocean Technologies.
