X-43A Hits Mach 7

quiggy writes "As previously reported, NASA tested the X-43A yesterday. The results are in, and the scramjet hit Mach 7, setting a new speed record. CNN is also reporting the story, with a note that a similar jet could be tested by the end of the year, hopefully reaching Mach 10."

Now all the need to do is make the scramjet safe

How safe are scramjets anyway I saw a test at an airshow one day and the whole engine overheated and blew up on of the operaters was very badly burnt. What would happen if this happened to a plane carrying a test pilot at 7000kph the result would be very tragic indeed.
