Rudder problems on the Pegasus booster have forced a postponement of the flight of NASA’s X-43A scramjet test vehicle. The flight is now scheduled to take place in late March or early April.
This flight hopes to build on lessons learned after the previous test aircraft was destroyed after a malfunction almost three years ago.
Incidentally, the B-52 that will carry the Pegasus/X-43A stack up to 40,000 feet for launching is the same aircraft that carried the X-15 rocket planes in the 1960s. Cool.
