The z-15's top speed is Mach 5. no way they said it was way faster than any other plane so it can't be mach 5. becuase i heard it was mach 9.7. 9000 mph.
but i just don't understand why NASA doesn't improve and turn it into a space plane because its not going to take a lot of work and if its really hard to control then how do they control the space shuttle. thats a beter way to make space travel.
