i don't disagree with any of that, i'm extremely skeptical that they will ever scale this up

however: there is, now. this is a civil aircraft flying supersonic, which is still some sort of interesting fact.

"Civil" supersonic aircraft is a designation, that's it. Like the other comment said - you can fly supersonic military jets with a civilian designation as long as the jet is deemed airworthy.

The real question is whether this will ever scale up to be a passenger aircraft. There are still a huge number of unsolved problems, many of which plagued the Concorde in the best of years. I don't think a scaled demonstrator is going to give people the confidence to denounce traditional passenger jets.

This is the first supersonic aircraft in a long time that started as a civilian one and was never intended for military applications. Loses points for the military engines though.

Still impressively cool.

Do none of the private jets like G6s or whatever fly supersonic?

nope.

commercial and private jets generally cap out around mach 0.9

i am very rusty on the economics and details of supersonic commercial flight, but the general gist as i recall is:

- going much faster scales up the cost of flying at a rate that's hard to justify for how much time it saves. there is less case in the 2000s for "having to be in london in 3 hours from NY" than there previously was, too.

- noise restrictions and such limit the usefulness of planes that are set up to fly that fast as people don't like being underneath constant sonic booms, so the routes that supersonic passenger flights were relegated to are mostly over water.

it is just way cheaper and easier to fly subsonic, and if you're on a private jet anyway it's not like you're uncomfortable while traveling.

i don't. i'm explicitly choosing not to be pedantic and instead hoping you'll take what i say as what it obviously is intended to mean and not as a very specific and accurate phrasing to be disassembled and torn apart without acknowledging the overall intent of the message.
