A new study by NASA’s Glenn Research Center has looked at the possibility of supersonic passenger jets. Its “high-speed strategy” is mooting commercial flights that travel at up to Mach 4 – over 3,000 miles per hour – starting with transoceanic routes.

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.

    I see where you’re coming from. Battery electric vehicles I think are a good example of trickle-down. It seems the R&D for electric cars affordable to wealthy people leads to new infra and tech for a changing power grid, buses, trains and bicycles.

    But two examples you raised:

    • corrective lenses
    • refrigeration

    have clear quality-of-life and health benefits. Supersonic passenger flights feel more like a luxury and convenience compared to food preservation.

    Hopefully in the development of reduced flight times between other sides of the world we perform research with impact beyond flight. Things like improved materials, fuel, aerodynamics that could be used for trains and trucks. I’m not an engineer but I hope it works like that!

      Faster transportation is quality of life too. Just like cars were, or railroads before them. Yeah, this one is currently worthless for anyone that isn’t rich. But if it proves successful it will become useful for more of us. Like you say, there’s also just the material and other sciences being done to make it possible that will filter out elsewhere. So much of early space exploration was Cold War dick waving, and now think about how much we rely on satellites. I couldn’t navigate anywhere without GPS, personally…

      People here take their hate of the rich (which is well placed) and aim it at all the wrong things. Don’t like the rich? Tax 'em more. That’s what I want. Higher income taxes and even a wealth tax on the top. And way more meaningful inheritance taxes. Instead they’re bitching about investments in science.

        Agreed. To be fair, I can also see where the frustration comes from. We see “deals with the devil” being made, but the (disappointing?) reality is tech progress often looks like that. Flashy stories with pie-in-the-sky ideas get headlines and funding. Meanwhile the boring, difficult work continues on in the background. From the outside it seems non-sensical and inefficient: why couldn’t they just invest money directly into GPS research without all the military stuff? But, fortunately, some amazing stuff does come out of it too.
