Measuring just under 19.6 feet long by 9.8 feet wide, the 4,000-pound Super Falcon Mark II is comprised mostly of carbon reinforced composite and can whisk a pair of people down to 393 feet below the surface. What's more, it employs a pair of stubby "wings" and a powerful, brushless DC motor to "fly" through the water at speeds up to 6 knots rather than simply sink to the bottom as a research vehicle, like Alvin, would. As with all personal submarines, Deepflight places passenger safety first and foremost. The Super Falcon is positively buoyant so that in the event that the engine dies, the vehicle will automatically float to the surface. Should it get trapped underwater, the vehicle maintains a pair of redundant, 12-hour life support systems as well as both underwater and VHF radios for communication. There's no word on pricing for the Super Falcon, but given the array of high-end accouterments—from its carbon fiber seats and fly-by-wire controls to optional integration with your yacht— and the fact that they're built to order, you can bet that it's going to cost way more than what you've got saved up. via Gizmodo.
