Happy Friday. Hope it’s not as hot where you are as it is here in Washington. How about some stealth jet porn to start the weekend. A tipster forwarded this clip showing Russia’s premiere stealth fighter, the Sukhoi T-50 PAK FA performing some decent aerobatics. The jet shown is likely the first of two test jets that have been built; the first one being used for aerodynamic testing while the second is reportedly being used to test out the aircraft’s mission systems. Enjoy!
