Launched from under the wing of a b-52, This plane quickly accelerated to unimaginable speeds of up to Mach 6.7 (4,520 mph). It also had the ability to ascend to altitudes as high as 67 miles (50 miles officially qualifies as outer space). This unique, ahead of its time rocket plane was nearly twice as fast as the SR-71 Blackbird, and almost as cool looking. Niel Armstrong was one of the first pilots of this amazing craft.
When my son and I were in Washington, DC. I snapped a few pictures of the first one ever to fly, which is on display at the Smithsonian Air and Space Museum.
