Check this out. Sukhoi's second T-50 PAK FA prototype stealth fighter took to the skies over Komsomolsk-on-Amur, Russia, this morning for a 57-minute test flight (or 44-minutes, depending on who you ask), according to Flight Global's Steve Trimble. The first T-50 is used as the aerodynamic test bed and the second jet is likely being used to test out the mission systems, notes Trimble. This flight comes a little more than a year after the maiden flight of the first T-50.
Here are more pics of the flight.
