New 'Underwater Plane' To Explore Ocean Depths

Necker Nymph

U.K. company Virgin Limited Edition recently announced the Necker Nymph, a three-person "aero-submarine" that can dive to depths of 36,000 feet – which is deeper than Mount Everest is tall. 
Unlike conventional subs, which use ballast to sink in the water, the Necker Nymph uses "uses downward 'lift' on the wings to fly down to depth," Virgin explained in a statement. Each dive can last up to two hours, during which time the "hydrobatic" Necker Nymph can perform dolphin-like flips underwater. An open cockpit provides a near 360-degree viewing experience. 

But unless you're incredibly wealthy, don't expect to experience a ride aboard the Necker Nymph anytime soon. The craft is only available if you rent Necker Belle, Virgin's 105-foot (32-meter) luxury catarmaran. The boat's weekly charter rate is U.S. $88,000. Rent the Necker Nymph will cost an additional U.S. $25,000 per week. Live Science
