Winged luxury submarines ‘fly’ underwater: I’d love to play in one of these.
“There are no valves, there are no gauges,” Hawkes said. “You just power up the thrusters, start your take-off run, put the joystick forward, then the nose goes down. The wings literally pull it down.”
That’s very different from conventional submarines, which basically dive by changing the ballast of the ship to make it sink.
“It’s not just that they look like airplanes, they actually are,” Hawkes said. “The machines we build underwater should look like airplanes, not submarines. Airplanes don’t look like balloons.”
So, to go down, you essentially have to have power. Hopefully they’re buoyant, so they’d float up to the top without power.
