Spy plane SR-72 to fly six times the speed of sound (VIDEO)








Defense contractor Lockheed Martin has unveiled a new spy plane. The SR-72 can fly at the hypersonic speed of six times the speed of sound.

It is the successor to the SR-71 Blackbird, which could only fly at the supersonic speed of three times the speed of sound.

RT's Sam Sacks has more information on what types of spying the new plane will be used for.
