The military does not have relatively silent supersonic flight. Only a few US military aircraft models are even capable of supersonic flight, and they're plenty loud. In order to avoid complaints they normally they only fly that fast over designated exercise areas.

The Boom aircraft incorporates some quiet supersonic technology but until they actually test it they won't know whether it's actually quiet enough.

I agree it's not a big deal over the Atlantic, but over the Pacific it could really be huge. Flights halfway around the world are looong . I've been to Australia once, and honestly not sure I'll ever be back. Just because it is a lot of time in a seat.

Over the arctic is probably the ideal route for flights like this considering it solves the problem of it being very very cold and normal flight sensors don't work in supersonic flights anyway so that wouldn't be an issue either.

I just love spending time in rush hour traffic \s

Having to drive in bumper to bumper traffic versus chilling in a large chair either working on a laptop, watching a movie or just sleeping (or well if you can't afford it in which case this is very irreverent due to ticket prices).

Large????

Have you done an 8 hour flight in economy? It's absolutely miserable. Noise pollution over the Atlantic affects literally noone.

It likely has an affect on whales and other marine animals as shown by a number of studies previously.

It's not like they are flying at 1000 feet above the ocean. at between 30-40k feet, if you can hear the jet engines, you are a lucky whale!

I would love a 2-3 hour faster flight over the Atlantic when I visit family. Or even more saving when going over the Pacific. But yes, it will be affordable for only a very small group of people I am not part of. I can't even afford first class for these flights.

Business class is the way, it would be much cheaper if first-class didn't exist since I genuinely never felt so out of place when being there. But I guess the amount of money you can get from first-class customers surpasses the amount you can get from business class customers.

Quick note that first class transatlantic doesn't really exist now. Lufthansa is the only carrier left iirc.

Even if the noise pollution can be solved (or, as others have said, just run it only over the ocean), I don't see how this thing wouldn't pump out an immense amount of CO2. It's definitely cool and would make flying nicer, but in an era where we're trying to decarbonize, get sustainable aviation fuel going, optimize flight paths to avoid contrail warming, etc... I can't lie, there is a big part of me that hopes it do…

> just run it only over the ocean If you look at the Overture's website ( https://boomsupersonic.com/overture ), it sounds like that's exactly what they are planning to do - it's advertised as "MACH 1.7 Cruise Speed, 2X Faster over water, 20% Faster over land" - if you take Mach 0.8 as the current cruise speed of subsonic jets, 20% faster would be just barely under the speed of sound.

The reasons why planes don't fly faster is efficiency.

It's not going to be an option, tickets will be tens of thousands of dollars

> tickets will be tens of thousands of dollars So about what a Golden Era international flight cost, inflation adjusted [1]. Not bad. [1] https://www.travelandleisure.com/airlines-airports/history-o...

It's what a private jet charter costs now. I bet rich execs prefer that despite the longer flying time. Getting direct to your destination, not having to rub shoulders with random people, stuff like that. It's also what killed the Concorde. Not enough comfort for the price.

The biggest problem in my opinion is the same problem concord had. You had to have two planes in every source location in case one of them has problems because your customers *will not accept a delay*.

That makes sense - if someone plans to fly London - New York for an important meeting, arriving there two hours late because the supersonic plane was switched for a subsonic one is not an option. Of course, nowadays they could just jump on a Zoom call instead, but where's the fun in that?

> don't want boom supersonic to succeed You’d prefer we buy them from China? If the physics works, it works and will happen. > military (and concord I guess) have had this technology for nearly a millennium Since the millennium, maybe? Charlemagne wasn’t flying in a supersonic PJ. And no, the military has not obviously solved large-body, sustained and fuel-efficient ( i.e. non-afterburning) flight. The USAF didn’t ge…

Supersonic flight will never be more efficient than traditional flights. And sorry I meant that I don't want any super sonic plane company to be successful.

'commercial' military planes - no, prototypes - yes.
