Most people have had dreams of flying. Graham Hawkes had dreams of flying -- underwater.

Hawkes has been in the business of building underwater craft for more than a decade.
In the early days, his company, Hawkes Ocean Technologies, built vehicles for researchers and moviemakers.
But in the past few years, the ultrarich have increasingly looked for cool playthings for their ocean adventures.
What better toy to have on the end of your 200-foot yacht than a submarine capable of diving to 1,500 feet below the sea's surface?
Whoops. Did we say submarine? It's a submersible that can “fly” underwater.
The Deep Flight Super Falcon looks like a fighter jet, with its thin body, two seats, two sets of wings and two tail fins.
“We just had to tear up everything we knew about submersibles and start again on winged subs -- underwater flying machines,” Hawkes said.
He said Deep Flight submersibles are designed to be more agile than any creature living in the ocean -- with the exception of dolphins.
The company says that because of the wings, the Super Falcon can go barrel-rolling with dolphins while traveling at speeds much faster than other private submarines.
The craft can stay underwater for up to five hours and travel at speeds up to 6 knots, the company says on its Web site.
The first client 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. Another model, which has open cockpits and cannot dive as deep as the Super Falcon, sells for $350,000.
Perkins, writing in Boating International magazine, said he joined the project to take the Super Falcon from prototype to a fully functional craft.
“Like some of my other projects, we didn't finish on time, but also like some of the others, the end result exceeded all our expectations,” he said.
The second machine is being built for Hawkes' personal use. A submarine driver wouldn't recognize the cockpit of the Super Falcon.
“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.”
He won't take credit for the idea, saying the idea of a submarine with fins and wings has been thought of before. The 1972 French comic book, “Tintin and the Lake of Sharks,” included a shark-like submarine with dorsal fins and a tail.
Hawkes said that although the idea of wings may have been obvious, “The prize goes to he that does.”
