Deep Flight "winged submersible" : up to 11km deep sea

"We have achieved our long term goals. We have proven underwater flight with the world's first full ocean depth capable (37,000 feet) submersible" said Graham Hawkes(Hawkes Ocean Technologies)

Deep Flight Challenger was made to enable adventurer, Steve Fossett, to set the ultimate solo dive to set world record depth dive.(37,000 feet).

Unfortunately Fossett perished in a plane crash before he could dive the submersible to record depth.
