A generous, mythological South Korean god. Thought to date back before Creation.

Or, just an average boy who goes to a posh English boys school in London.

Ok I felt that my earlier definition about the Su-47 didn't cover much. The Su-47 is an deraitve of the Su-27, the Su-47 and MiG 1.44 are both test beds for the Sukoi PAK FA program, it's first name was S-37. The wing design is not like most other aircraft, the Su-47 has forward swept wings, and titanium aloys used for the wing construction, normal materials used like on most aircraft would just come apart when the Su-47 pulls manuvers. The Su-47's cockpit was designed to the pilot would have the most comfort while pulling high G manuvers or ejecting, it also has a low-travel side mounted control stick, the seat is inclined at an angle of 60 degrees, so the pilot can pull high G manuvers and still stay in control of the aircraft.
