Spy Plane Gets Anywhere in the World in 1 Hour

Lockheed Martin is working on a new hypersonic spy plane that is capable of flying 6 times faster than the speed of sound -- that's more than 3,500 MPH. This plane, named the SR-72, will fly as high as 80,000 feet and be able to get anywhere in the world within an hour. Lockheed says this will be a game changer for military surveillance. Good to know for when we're running late.
