NASA ScramJet Breaks Speed Record!

It rocketed to 10 times the speed of sound: 6,800 mph! The X-43A-a supersonic combustion ram jet made the run over the Pacific Ocean. It was so fast! I would be scared to death. It uses the oxygen it uses from the air instead of carrying a heavy tank. Scramjets could be used in the future to shoot passenger planes into space. Explain how NASA felt.
