PERSONAL SUBMARINE

A deep flight personal submarine built for Tom Perkins' Maltese Falcon yacht. This submarine named "deep flight". It's a submersible with a pair of wings that can "fly" underwater. The sub does not have ballast tanks, but dives because of its forward speed---like a penguin does when it hunts. It more like a fighter jet, with thin body, two wings, two seats and two tail fins.

"The sub will have an operating depth of 400 feet, a speed of 5 knots and an underwater time of roughly 4 hours on a single battery charge. Like the airplane it will do rolls, loops and can "porpoise" when it surfaces (the speed in a power ascent can exceed 10 knots)."

Its first client is for the Super Falcon was venture capitalist Tom Perkins, who wanted a toy to keep on his mega-yacht, the Maltese Falcon. The base price: $1.3 million. Expensive? They are also available in another model, which has open cockpits and cannot dive as deep as the Super Falcon, sells for $350,000. For more information and to see the Deep Flight in action, go to CNN
