this is significant because it's the first civil aircraft to reach that milestone since the ending of the concorde program.
And how is this a civilian aircraft? It is a cool one-off single seater with three military engines (oops, civilian engines derived from military and used in business jets - still not cheap for a one-seater). Two-seater for some definition of "technically". But perhaps they can sell a few of these to private pilots and then it would be a supersonic civilian aircraft. One pilot and one passenger if we insist on making it a business jet.
Which means, for example, that even this small private company knew pretty well what to look for in wind tunnel tests and other materials work. Their first transonic and supersonic flight was stable, did not destroy the aircraft, did not kill the engines, etc. Even, presumably, broke through the sound barrier the first time they tried - and was fully expected to.
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.
This is the equivalent of a hand drawn ui mockup for a future “AGI workstation”, while not at all addressing the “AGI” part
however: there is, now. this is a civil aircraft flying supersonic, which is still some sort of interesting fact.
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.
Still impressively cool.
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.
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.
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.
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...
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.
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
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.
West bound being able to leave the office at 6pm and be in New York to pay the kids to bed is great.
Worse: drag in the transonic regime is generally worse than subsonic or supersonic.
Supersonic flight will be the preserve of the 0.1%, but the vast majority of private jets can't fly trans-continental (without stops along the way) and there are people out there paying $50k per flight for Etihad's The Residence suites. So, yes, there are people who will pay for this.
Air travel is popular, but extremely price sensitive. Ryanair and its ilk have shown that people will suffer humiliation to save even $50 on ticket prices.
Supersonic will have to serve the rich, who are willing to pay to fly private. But how big is that market? Especially if you’re still going to raise prices 2-3x?
people don't mind the experience of flying in a plane or the time it takes for the most part - they mind being uncomfortably crammed into a seat for hours on end with another person spilling into their lap in a loud, stuffy cabin. otherwise, it's just hanging out in a different place than you usually do.
at the point you're paying for a resort hotel room with a shower, bed, privacy, internet and a tv in the air... who cares if you spend a few extra hours? the only example of a supersonic airliner that i can point to, the concorde, was actually fairly uncomfortable and cramped because of the way it was designed. it's likely (though i've been wrong before) that future supersonic planes would make similar tradeoffs to try and minimize weight and drag and maximize fuel economy - you will trade comfort for speed.
i think most of the people you're talking about would prefer 8 hours in a private hotel room (or full on private jet) with a full bar, bottle service, a shower and fancy meals to 2-3 hours cramped in a relatively small cabin after the novelty wears off. given how much easier it is to effectively meet across the ocean without traveling, the market for ultra-fast flights to get a one-day trip over with is also likely smaller.
i can't say i know any of these facts for certain, but previously when discussing the return of supersonic flights with folks who know better than i, this was the general sentiment. it makes reasonable sense to me on its face.
Anyone making $1+ mm / year is not in regular private-jet territory. That leaves commercial, which doesn’t have suites on most routes. (Most domestic routes don’t have lay-flat options.)
In between you have a $5k to $25k window in which something like Boom could operate. Same, dense domestic business seats. But lower service costs because you don’t need to serve a coursed meal on a 2-hour flight.
Certainly they're fast, wikipedia says the the G650 can get to mach 0.9, but it's called the sound barrier for a reason. https://en.wikipedia.org/wiki/Sound_barrier
This sort of pessimism to dismiss this achievement is exactly how to lose and stay comfortable.
Ladies and gentlemen, dismiss the above take.
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 great: you leave in the morning and you arrive, local time, before the local time of your origin point. But traveling east bound isn't that great: you still have to leave in the morning and you land in the evening, so the only thing you gained is a shorter flight time but not a full day of work or shopping or what not.
So on regular flights (because Concorde was profitable, at least on the French side, thanks to charter flights), people would fly Concorde to go to NYC and fly back on a red eye...
As someone who worked for and flew on Concorde, I think what they're doing is amazingly cool though and I hope they succeed. But I'm still unsure what the long term plan is...
OP is being downvoted for saying there is still not supersonic civil aviation on a video showing a civil aircraft going supersonic.
F-BTSD did it:
- westbound in 32 hours 49 minutes and 3 seconds on 12/13 October 1992, LIS-SDQ-ACA-HNL-GUM-BKK-BAH-LIS (Lisbon, Saint-Domingue, Acapulco, Honolulu, Guam, Bangkok, Bahrein, Lisbon)
- astbound in 31 hours 27 minutes and 49 seconds on 15/16 August 1995, JFK-TLS-DXB-BKK-GUM-HNL-ACA-JFK (New York, Toulouse, Dubai, Bangkok, Guam, Honolulu, Acapulco, New York)

Having the tech sounds funny. In some abstract way maybe. Actually being able to build a supersonic airframe and everything connected.
Both the Cessna Citation TEN and the Bombardier Global 8000 were taken supersonic during test flights, as they have to demonstrate stability at speeds of M0.07 greater than max cruise.
They aren't certificated to do it in service, but structurally and aerodynamically have no problem.
Long-range business jets have been pushing aeronautical boundaries well beyond the mundane airliner state-of-the-art.
