"in a long time" kinda doesn't matter to me. America hasn't built a supersonic bomber "in a long time", you'll have to excuse me for not caring. The value of such a weapon is dubious and only made sense in a hype-laden Cold War environment.

Similarly I don't think we've learned the lessons of the Concorde yet. Not only do people not need hypersonic flight, it's going to create a premium class of hydrocarbon emissions that is already bad enough with passenger aircraft. Progressive countries will ban operation (much like they did with the Concorde) and routes will have to be changed. Removing the afterburner and making the boom quieter simply isn't going to bring these skeptics onboard, and they're right to remain skeptical.

> Not only do people not need hypersonic flight,

We do. It takes me more than 14 hours and two flights to visit my son in Brazil. Even if there was a direct flight, it wouldn't be much less than that.

At this time, very few people visit places more than 10 hours away from their homes. Knowing places faraway and different expands one's horizons. You learn that there are different ways of living, different ways of thinking, and that not everything that's different is bad, threatening, or broken, or "underdeveloped".

The more people know each other, the better we are able to work together. And the better we understand we are all on the same boat, regardless of what our governments say.

Are you willing to pay 10x the price for 1/2 the travel time? And even if you are willing to pay that, are there enough people besides you willing to pay that to sustain this business model?

I'd imagine most people in this wealth bracket would just fly private. I'll happily spend 5, 10, 15 hours in a plane if I don't feel like a sardine in a can.

The Concorde failed for a reason (actually multiple reasons). And they actually had an engine supplier - the hard part - whereas Boom has been shunned by the entire industry for this critical part.

I suspect if you were to draw a Venn diagram of "people who had never visited a place more than 10 hours from their home" and "people who could afford a ticket on a Boom Supersonic airliner at their target profitable ticket price range..." there wouldn't be any overlap.

You don't need hypersonic travel to discover places far away, and the target market who are so busy it's worth paying extra so they can get back to the US from their European office without staying overnight aren't going to be doing much of that anyway...

Boom will only be the first. Other supersonic airliners will happen once Boom validates the market. We can do a lot better than Concorde did now, with higher efficiency engines and lighter materials.

I just saw the other day China developing a rotating detonation ramjet. I guess missiles will come first, but, eventually, China will want to cross their 21st century empire faster than current airliners.

There's a difference between "better than Concorde", which isn't exactly a high point of efficiency, and defying the laws of physics to make supersonic flights so cheap they can operate flights between origins and destinations that aren't commercially viable to fly direct at the moment (like your trip to Brazil) in sufficient comfort to attract people that don't do long haul at the moment

The barrier to most people not to visiting places that are very far away isn't "flights are 40% longer than ideal". 40% cheaper flights would open up the world more, but this is a step in the opposite direction

If there’s no direct flight now it seems unlikely there’s enough demand to justify a supersonic flight.

[rbanffy]

I can take one subsonic leg to the nearest hub (Amsterdam, London, Paris) and fly from there. It’s that second leg that kills the joy of travelling.

[bangaroo]

as a person who likes airplanes (and airliners in particular,) i think it's cool that a commercially-focused aircraft manufacturer has managed to return to a type of flight that has primarily been relegated to military operations for a very long time

today i am not thinking any further ahead than "wow, they did a really cool thing and made a supersonic test platform for a commercial airliner."

there will be lots of future questions and concerns but we are far off from them, because they are not even close to scaling this up and there are so many gaping holes in the plan that i don't take it seriously at the moment.

i just think the little plane is neat.

[rbanffy]

I can't wait to see NASA's one. What I really hope is Mach 2 at altitudes higher than the Concorde, in order to minimize sonic booms on land. Even if we never get to fly supersonic over land again, a Mach 2 plane that can cross the Pacific would be incredible.

[creer]

The work to minimize or delete sonic boom - that's an important one. And it's a NASA project.
