  1. On November 16th, 2004, NASA took a major step toward redefining high speed flight.
  2. The X-43A, a small experimental aircraft, was developed to test an ambitious idea
  3. to prove that an engine using oxygen from the atmosphere for fuel could push an aircraft to hypersonic speeds.
  4. The plan for this flight was to exceed Mach 6.8, or about 5000mph.
  5. The X-43A, part of the Hyper-X program, was a joint effort between NASA's Armstrong and Langley Research Centers.
  6. The goal was to demonstrate the technology that could revolutionize flight, space access and reusable space launchers.
  7. The X-43A was attached to the nose of a Pegasus booster
  8. rocket and mounted beneath the wing of NASA's legendary B-52B.
  9. Teams worked tirelessly to ensure everything was ready for what could become a historic flight.
  10. With preparations and final checks complete, The B-52B took off from Edwards Air Force Base
  11. and headed west over the Pacific Ocean.
  12. At altitude, the Pegasus booster rocket and X-43A were released.
  13. 3-2-1 launch, launch, launch- sequencer reset.
  14. Good release.
  15. Once ignited, the rocket carried the X-43A into the upper atmosphere.
  16. Then, at precisely the right moment, the X-43a separated and its supersonic combustion ramjet engine powered up to achieve hypersonic speeds.
  17. In less than 10seconds, the X-43A made history with a new speed record for an air breathing jet aircraft.
  18. It reached Mach 9.6, or about 7000mph.
  19. This was more than just a test flight.
  20. It was a glimpse into the future of aviation and a moment where research, collaboration and ambition came together and flew.
  21. It was a success that laid the groundwork for hypersonic flight.

Описание от NASA (по-английски)

NASA took a major step toward redefining high-speed flight on Nov. 16, 2004, when the X-43A – a small, experimental aircraft – proved that an engine drawing oxygen from the atmosphere could propel an aircraft to hypersonic speeds. During the flight over the Pacific Ocean west of California, the X-43A set the world speed record for a jet-powered aircraft, reaching Mach 9.6, or nearly 7,000 mph. The mission originated from NASA’s Armstrong Flight Research Center in Edwards, California. Click here for the latest on NASA’s hypersonic research:
