This is so exciting. The only ones I know working on this are Boom (unless they’ve pivoted entirely into AI DC turbines). Between this and the wind-turbine-blade air transporter it’s an exciting time for aviation. Now if we can only transition off leaded fuel!

Why is this an exciting time for aviation? Or more specifically, why should I (a person who never spends more than $2,000 on air travel) be excited?

your response doesn't help you make your case. instead of complaining and namecalling the commenter, how about engaging with the comment as the others are doing. if you don't want this place to turn into reddit, then you should not act like you are on reddit.

the mark of a good discussion is that you can respond to a contrary opinion without getting triggered by it.

you seem to have decided that this is progress, but others are clearly not convinced. for myself i don't know if this is the progress we need. but then i believe that the most important progress we need to make is to be more civil to each other and work towards social unity, so that we can discuss technical progress without constantly getting angry at each other, because that, in the end is the biggest obstacle to any progress.

so instead of being part of the problem and making things worse by complaining, try being a part of the solution and engage with the commenters in an earnest but well meaning manner. disagree, ask them to substantiate their claim, or provide counter evidence, but don't derail the discussion with a futile rant.

Earlier quoted context omitted.

By immigrating, your parents(and you) took on the shared responsibility for the countries wrongdoings and great deeds. When people talk about this stuff, it isn't about apportioning blame. I'm not big on the stolen land thing because it's turtles all the way down, but this idea of divvying up blame makes no sense. We are all citizens.

I had no agency in being born and raised here. Are you saying that by staying in this country, I’m now responsible for stealing land 200 years ago? And my responsibility for stealing this land means I can’t be upset about supersonic jets?

we are as a whole responsible for making the world a better place. everyone with their capacity and their ability to do something. now, i am not trying to judge what you are doing, nor am i suggesting you are not doing enough already. that's not the point. by living in the US you are however in a better position to work on this particular cause than i am living elsewhere. not because you are responsible in the sense of being guilty, but you, and everyone else in the US, is responsible in the sense of there being a wrong that needs to be righted.

otherwise we could just say nobody is responsible because it was all someone else. but if that someone else is not alive anymore then it is up to the current society to step up and fill in. guilt is not required. would you help orphan children whose parents died in an accident even if you were not involved? then why not help these people who have been deprived of their land and are now without the ability to govern themselves? the people of israel got their ancient homeland back after 2 millennia and were allowed to form a sovereign nation long after anyone could reasonably be called responsible for taking their land away. so why not do the same of the native american nations too?

the question is not: are you responsible? but: is there a wrong that needs to be fixed, and are you in a position to contribute to fixing it?

but to your last point: this has nothing to do with being upset about supersonic jets. actually i believe as far as it is reasonable native americans would be upset about noise pollution too, so you would probably be arguing their side here anyways.

Increased adoption will put price pressure on traditional flights making them more affordable

There is a substantial noise beyond the initial boom which is very loud even relative to the main boom. But even just a half second of a car horn going off right next to you every so often is intolerable.

People finding a way to tolerate what was previously considered intolerable is pretty much the story of civilization.

If supersonic flight is so expensive that less than 1% of the population can enjoy it its not clear why the rest of us ought to tolerate it

If you really want to make an impact on the noise floor, ban gasoline leaf blowers.

I was 100% in your camp until my neighbor bought an electric blower. The loud, high pitched whine is somehow louder and more ear piercing than a gas blower.

Gas blowers pollute which is the primary reason to ban them.

0.11 pound per square foot is what is being proposed. That's 108 decibels. Which is between standing next to a lawn mower and standing next to a car horn. I don't see how anyone will tolerate that in practice. https://www.omnicalculator.com/physics/db

> That's 108 decibels. > I don't see how anyone will tolerate that in practice. Oh! Really? https://earinc.com/gunfire-noise-level-reference-chart/

...yes, really? Gun fire is indeed stupendously, dangerously loud, which is why we have suppressors and heavy hearing protection for them. And there are indeed significant public/legal fights around outdoor gun ranges that end up near habitation (even if it's not the range's fault at all but rather because construction moved towards it).

So I'm not really seeing how that's an argument that people not wearing earpro would be fine with regular 108 dB booms over where they live/work. People aren't happy even about small engine noise and rightfully so, and it's one of a few core reasons for switching to electric.

As I understand it the noise pollution stuff is due to really old tech. The new stuff should be much better performing to basically eliminate the sonic boom and the regulatory changes are reflecting that. On a site like HN this kind of progress should be praised not denigrated as antisocial.

Is that why you flagged the parent comment for critiquing progress?

If sonic booms become a routine occurrence over America, I expect to see a backlash against supersonic flight unifying everyone between chemtrail conspiracy theorists and the greenpeace. The anti data center backlash we have today will look like child's play.
