Why should James Bond be the only one with a swanky aero sub? If you've got the cash, Sir Richard Branson is more than happy to lend you his for the day.
The Necker Nymph, which resides on Branson's luxury catamaran, the Necker Belle, is an open-cabin three-seater sub. It dives down to a depth of 30m, a top underwater speed of six knots, and can remain submerged for up to two hours.
Both passengers wear normal scuba breathing gear — no, you don't get to drive this one-of-a-kind winged submarine, there's a pilot for that. A day-long rental will set you back $US2500 and unfortunately does not include Barbara Bach. [Necker Belle via Gadget Review]
