Is America's Spy Plane Back — and Hypersonic?

The SR-71 Blackbird spy plane may be back

and faster than ever.
Or maybe not. Ambiguous wording at an aerospace-conference presentation last week suggested that the SR-72, a successor to the infamous Cold War spy plane, might already be in production, but neither the military nor the plane's possible maker, Lockheed Martin Corp., is talking.
Bloomberg reported that Lockheed Vice President Jack O'Banion projected an artist's conception of the hypersonic SR-72 during a talk at the annual SciTech Forum of the American Institute of Aeronautics and Astronautics in Florida on Jan. 8. Standing by the image of the sleek gray aircraft, O'Banion reportedly spoke about recent advances in computing and design and then said, "Without the digital transformation, the aircraft you see there could not have been made."
