In July, Lockheed Martin completed the build of NASA’s X-59 test aircraft, which is designed to turn sonic booms into mere thumps, in the hope of making overland supersonic flight a possibility. Ground tests and a first test flight are planned for later in the year. NASA aims to have enough data to hand over to US regulators in 2027.

        In North America.

        For the EU the biggest issue is all of the national operators being insane in different ways that makes it harder and more expensive than it should be to cross borders by rail a lot of the time.

      Price per km of track goes up exponentialy the faster you want to go, which means they will either have expensive tickets or will be unprofitable.
