Russia Is Developing a New Fighter Jet That is Hypersonic and Flies in 'Space'

Outer space is generally considered to begin sixty-two miles high, or 327,000 feet. In 1963, a NASA X-15 aircraft reached an altitude of sixty-seven miles high, which remained a world record until the Space Shuttle (considered an aircraft rather than a spacecraft for this purpose) first flew in 1981. However, the X-15 was a rocket plane and the Space Shuttle a glider mated to giant rocket boosters.

For the myriad forces flying over Syria, it is clear that the airspace might not be as permissive as some might have believed.
