The Lockheed SR-71 Blackbird spy plane never flew in Russian airspace... officially.
The Blackbird could reach a top speed of 2,200 mph and a ceiling height of 85,000 ft - enough to see the curvature of the earth. They outmatched everything the Russians could throw at them... except the MiG-31. So when one angry Red sets his sights on the elusive "White Comet" pilot, it's a battle to the death at the... EDGE OF THE SKY!
