Venus Aerospace showed the concept of a supersonic civil aircraft Stargazer.

It will accelerate to Mach 9 and will be able to deliver passengers from New York to Tokyo in an hour with a maximum speed of 11 thousand kilometers per hour. For this, a combo of conventional aircraft and rocket engines will be used - the jet will fly almost in space. There is only one nuance - we are talking about a business jet for 12 people.
