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.

Are you going to ride the bus from NYC to L.A.?

Just because buses and trains don't make sense for trans continental journeys, doesn't mean they can't be used for shorter journeys. There's a bunch of areas in North America where is does make sense and could eliminate many flights.

That's true. They're talking about building a high speed rail from Portland to Seattle right now, and I think that would be awesome. Decades ago California spent billions to build a high speed rail from Fresno to San Francisco, which would have solved a lot of problems for both cities, but as far as I know, they never even laid a single mile of track.

It would still take you 2-3 days, assuming normal operation with stops along the way. If the fastest train that exists on the planet right now ran from NYC to L.A. and was able to go from 0 to top speed instantly, and maintain that speed the entire trip, it would still take 10 hours to get there. Trains don't operate that way though, so realistically it's 3 days worth of travel. It's almost 3000 miles to cross the USA.
