I’D LIKE TO GET A RIDE IN ONE OF THESE: Son Of Blackbird. “In a detailed report in the Nov. 4 edition of Aviation Week & Space Technology, Senior Editor Guy Norris lifts the wraps on the SR-72’s cutting-edge design, including a propulsion breakthrough that would allow the aircraft to fly twice as fast as the Blackbird — six times the speed of sound — but still take off from and land on a runway like a conventional aircraft. Lockheed Martin and partner Aerojet-Rocketdyne have been working in secret for seven years on the concept, which centers on integrating an off-the-shelf turbine with a scramjet to power the aircraft from standstill to Mach 6.”
