A US team proposes a propulsion system that could allow air travel at speeds of 21,000 km per hour (Mach 17)
A novel propulsion system developed by a team from the University of Central Florida and the U.S. Naval Research Laboratory allows for flight speeds between Mach 6 to Mach 17 (about 4,600 to 13,000 miles per hour), and the technology was inspired by supernovae, the explosion that occurs when a star dies.

In a paper published on Monday in the Proceedings of the National Academy of Sciences, the research team was able to stabilize the detonation required for a jet engine to reach hypersonic speed. Creating a “hypersonic reaction chamber” inside a modified jet engine, the system could allow for speeds reaching 13,000 miles per hour, or Mach 17.
Is it time to finally commercialize the Aurora?

I would hate to be one of the passengers when something goes terribly wrong. :?

But then, it'll be quick.
