Preamble

In the second  world war had appeared a lot of the scientists and thechnology investigators of all times, above all in the military camp, but at the end, some of the best scientist of  the "losers" were" judged by the "winners".

But it didnt stop there, the scientist continued with the weapons ivenstigation, URSS and EE.UU started a competition, they had built a lot of airplanes, tanks, submarines and bombs, the nuclear bombs, gas bombs and other, each other of the sides of cold war had started a technology carrer, URSS had conquest the space, when EE.UU conquest the moon only some years later.
This competition continuous after the cold war and afther the end of the URSS, and thats when the fifth generation of military airplanes came, Russia and a EU had invented the F-22 raptor and the PAK FA, both, the best airplanes of our times, but the PAK FA is the objetive of this blog, because we want to see some aspects of this machine.
