tcgardner writes “NASANews is reporting the testing of their new scramjet technology. The first of three tests will drop the X-43A test plane from a B-52 and accelerate it to Mach 7 with a Pegasus booster rocket. At that point the scramjet will engage and hold the plane at Mach 7. Other tests will take the plane to Mach 10.
The potential here is enourmous. In the future we may be able to launch,fly, and land our spacecraft as easily as conventional aircraft of today.
This is part of NASA’s Hyper-X Program.”
