the sr71 blackbird already can make it from NY to LA in under an hour and i dont thinhkl that breaks mach 4. mach 18 would put you around the world in almost an hr. but i dont think thats feasable for passenger flights because of the G forces needed to get up there, up to that speed, and slow down from that speed would kill some people.
differences between this and the concord? well its a different design by different engineers, its gonna probobly be like the 747 and the airbus. both big commercial jet liners, just designed different and by a different company. and the concord was made in the late 60's, this is 40 years later. we have better technology
