The speed which is required to travel through time
(142 kph)

Celebrated each November 5th, Back to the Future Day is our opportunity to recognize Doc Brown's discovery of the Flux Capacitor, the device that makes time travel possible. Back to the Future Day is celebrated by wishing everyone a Happy Back to the Future Day, and updating your social media networks statuses accordingly.

On November 5th, 1955, Dr. Emmet Lathrop Brown (Doc Brown to his friends), was attempting to hang a clock in his bathroom. As he reached over, he lost his footing , slipped from the toilet that he was standing on, and struck his head against the side of the sink.

Unconscious, Doc had a vision. And that vision was that of a Flux Capacitor — the device that makes time travel possible.

Requiring 1.21 gigawatts of electrical power and to be moving at a speed of 88 mph (142 km/h) the Flux Capacitor allows one to move forward or backwards in time.

Dr. Emmet Brown, on this day in history, we salute you, and remember your red letter date in the history of science!

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.
