Hence why everyone thinks supersonic passenger planes are a bad idea. Lots of profitable military supersonic planes, but every existing example of a civilian supersonic plane is only justified as a Cold War dick-measuring contest.
How do you measure the profitability of military aircraft?
Does Boom have a public roadmap? How much of a jump is it between building a fighter jet clone and building a passenger sized aircraft? I suspect it’s a massive jump. How much of the technology and testing is transferable? I also suspect not much. They’re going to spend an immense amount of money testing this aircraft, will it get them closer to passenger service as a result?

And thats a good thing. The world can’t afford the carbon (equivalent) emissions of many people flying supersonic.
How cool is that, hopefully will pressure Airbus into developing one too. So far they did silly concept vides only. I'm also quite worried about Airbus after winning against Boeing becoming complacent since Chinese or Russians are not even close.
This is slightly off topic, but why cant we start rebuilding Concorde? Wouldn't it be much easier to rebuild using modern technology? And try to get Mach 3 over the Atlantic so London to New York could hopefully be under 3 hours including take off and landing.
You can either a) rebuild the Concord or b) use modern technology.
If you use modern technology, its not a Concord anymore.
And you can't magically go Mach 3 just because you say its 'modern'. What existing engine can do that? And even if you had an engine, a Concord will not do that anyway.
So really you are talking about developing a whole new plane. And that's gone cost 10-20 billion $ and including the engine like quite a bit more.

Airfares have dropped precipitously over the last fifty years: https://simpleflying.com/50-years-airfares/, and it's quite possible that the trend will continue.
Conversely, the speed of commercial flight has barely changed over that time (with the exception of longer flights reducing stops). Boom is innovating in this area and bringing supersonic flight within reach again -- I for one think that's something to be celebrated.
The Concorde wasn't a civil aircraft?
Also in the 60s a DC-8 was made to go faster than Mach 1

> there hasn't been supersonic civil aviation There still isn’t, and this is not a very interesting stepping stone. We already knew that we could fly a plane quickly. This company has no engines for their allegedly full scale plane. The last manufacturer dropped them a few years ago, and there has been no movement in that direction. This demonstrates the easiest part of what they’re trying to do, not the hardest. Thi…
I'm not sure why you're being downvoted because you're right: they have the technology, they don't have an engine, and this just looks like a civilian version of a fighter jet pretty much (except it has 3 turbojets). And what people always fail to mention when it comes to supersonic flights is one of the main issue is neither a technological nor an economical one nor a supersonic boom one. Traveling west bound is gre…
Having the tech sounds funny. In some abstract way maybe. Actually being able to build a supersonic airframe and everything connected.

this plane doesn't look like it was made to produce a low boom. It has a very distinct von Karman ogive [1] fuselage and typical delta wings. I would guess that it's shape is primarily optimized for fuel efficiency at 1.5 mach or above. If you take a look at NASA's low boom demonstrator [2], you can see that it's much skinnier and the nose is crazy elongated. This is intended to break up the bow shock into multiple p…
Silly question, but would it be feasible to just equip a plan with a telescoping nose merely for this effect that could be deployed prior to supersonic flight?

Where did you get that idea from? airlines transported 4.4 billions of passengers in 2023 and 5 billions in 2024 [0]. No matter how you slide those figures, it represents more than just a minority of world population.
> Let me know when this proves economically viable for low cost airfare
Since when this is the goal of commercial supersonic travel?
