United Airlines Wants To Bring Back Supersonic Air Travel (nytimes.com) 131

The airline, which plans to buy planes from Boom Supersonic [Editor's note: the link may be paywalled; alternative source], a start-up, could become the first to offer ultrafast commercial flights since the Concorde stopped flying in 2003. From a report: The era of supersonic commercial flights came to an end when the Concorde completed its last trip between New York and London in 2003, but the allure of ultrafast air travel never quite died out. President Biden mused about supersonic flights when discussing his infrastructure plan in April. And on Thursday, United Airlines said it was ordering 15 jets that can travel faster than the speed of sound from Boom Supersonic, a start-up in Denver. The airline said it had an option to increase its order by up to 35 planes.

Boom, which has raised $270 million from venture capital firms and other investors, said it planned to introduce aircraft in 2025 and start flight tests in 2026. It expects the plane, which it calls the Overture, to carry passengers before the end of the decade. But the start-up's plans have already slipped at least once, and it will have to overcome many obstacles, including securing approval from the Federal Aviation Administration and regulators in other countries. Even established manufacturers have stumbled when introducing new or redesigned planes. Boeing's 737 Max was grounded for nearly two years after two crashes.

    Two words: Energy Costs.

    The greater amount of energy required for supersonic flight will make this a luxury for the rich until the energy powering passenger jets is massively cheaper in general. Don't forget that Concorde tickets were ludicrously expensive, and so was the aircraft, even though they were almost given to the airlines.

        The laws of physics haven't changed, technology that could be used to make a more efficient supersonic airliner could also be used to make an even more efficient subsonic airliner, yet we haven't made those so cheap that airline passengers feel like they'd be fine with paying many times as much money for a faster flight. Meanwhile the fuels airliners run on are far more expensive than in 1969.

        Boom is making a private jet with no delusions of mass affordability, notice the difference - not to say that investor confidence should be any measure of merit.

          As you can see, up to 2009, airfare AND real cost per mile both fell by 50% since 1979 (40 years). So, despite laws of physics not changing and the price of oil more than doubling [macrotrends.net] between 1979 and 2009, the prices fell.

            Modern airliners have a far lower fuel consumption because they have high bypass turbofans. These are only usable for subsonic speeds and modern airliners on average are designed for lower cruise speeds than back in the day.

          The laws of physics haven't changed

          The laws of physics didn't change when computing ran on vacuum tubes, and that didn't prevent the world to move to transistors, and from transistors to microprocessors.

          The creation of better/more efficient supersonic airliners is not about violating the laws of physics, but finding better ways to make it happen. The costs of operations and materials today are not the same as how they were in 1969. Different constrains.

          technology that could be used to make a more efficient supersonic airliner could also be used to make an even more efficient subsonic airliner,

          The development of more efficient subsonic airliners is not mutually exclusive or more efficient supersonic travel. Unless someone finds a way to fly over the athmosphere, a sonic boom will be a concern and subsonic travel will be required across continental mass lands. In this case, supersonic travel would be limited for transoceanic/transcontinental travel.

          This isn't a zero-sum game.

          • Technology can improve - but it improves for a reason. Transistors, then ICs were new technologies. There were lots of demonstrations of better performance than vacuum tubes. Its not impossible that there has been some breakthrough in aerodynamics, but I see nothing to back that up. If the company has developed a new design with 2X the lift to drag ration of previous supersonic planes, that's great, and I wish them luck - but I'm not going to believe it until I see it fly or see a refereed paper.

        • The laws of physics haven't changed, technology that could be used to make a more efficient supersonic airliner could also be used to make an even more efficient subsonic airliner

          That's not necessarily true. Drag forces decrease significantly as hypersonic speed increases. There could be legit efficiency gains at the higher ends of hypersonic speeds that would be unattainable at subsonic speeds.

        • The F-22 is capable of super cruise supersonic travel without afterburners.

          The Concorde used afterburners.

          That by itself will save tons of fuel. The big issue is still sonic booms. Which means you don't start going faster than sound until x miles off shore.

          Which limits utility.

          • The Concorde only used afterburners for takeoff and to quickly pass the transonic area. It flew without afterburners the rest of the time and was supercruise capable.

        It's not 1969, but the laws of physics haven't changed since then. You still have to burn a lot of fuel to go through the air faster than sound and the plane is still going to be small and vibrate in the turbulence. Some aviation technology has improved, but climate change is a bigger problem than it was half a century ago, and getting to, through and back from airports takes more time than ever, so supersonic may be slashing total trip time across the Atlantic from, say 10, hours to 8 hours.

        I'm pretty sure their backers have examined their figures in far more detail than you ever will.

        Perhaps. But the airline industry has a long history of stupid investments and bailouts, so we should not automatically assume that they know what they are doing.

        Concorde was a financial black hole. The government subsidies were about $8000 per passenger. British and French taxpayers paid billions to help rich people waste money.

        The lesson from Concorde is that far more people care about low ticket prices than about speed. Those who can afford to pay more fly on private jets to avoid ground delays rather than paying for faster airspeed.

        • If you are rich enough to afford Concorde tickets, you are probably rich enough to charter a private jet. Skipping the security lines, schedules, and connecting flights saves more time than any supersonic flight could.

                But your example is one of the many cases why most Europeans consider the USA a third world country.

                The longest lines are in Bangkok, not because of "security" but passport/immigrations and other silly bureaucracies. So I spent with bad luck 30 mins in the line for passport (into and out of the country), and 10 minutes max, usually 5, at security.

                When I fly out of Europe no one cares about my passport, so I only spent 5 - 10 mins insecurity.

          Including the whole program cost of course it could be different, but it's not really the whole picture either becaues the program got cut down significantly unexpectedly (well they should've seen the sonic boom issue coming, really) so there wasn't the volume necessary to for more reasonable unit costs.

            From here [airlineratings.com].

            From the link: "the total write-off for the British and French governments was $34 billion, which works out to a taxpayer subsidy of a staggering $8000 for every passenger who ever flew on the Concorde.

            With $34B in taxpayer handouts, almost anything is profitable.

              The $34Billion write off there was for the entire program - British Airways and Air France bought the majority of their fleet at full list and then received a handful of other airframes which were not taken up by purchasers after the fuel crisis in the 1970s. So the majority of each fleet was not a subsidised purchase - the manufacturer didn't make any money, but that doesnt mean that the write off was a subsidy for

Concorde was a pretty small aircraft (~100 pax), so if they can get a larger one that can go ~Mach 1.5 or so instead of the typical Mach 0.8 or so (and be more efficient than Concorde's M 2+), you're talking about significant time savings off of long-haul flights.

Basically the Concorde could be stretched by 25% until it hits this limit so you get maybe 33 rows instead of 26. Even if lowering to Mach 1.5 would make a larger tube with 5 abreast possible, it still only gives you 165 passengers at best while stretching the aircraft to its maximum possible length, requiring a gate usually rese

          It was, at first. Then they said fuck it and decided to charge enough to cover the real costs, and people still paid it. Oh, here's the line from Wikipedia:

          Research revealed that passengers thought that the fare was higher than it actually was, so the airline raised ticket prices to match these perceptions. It is reported that British Airways then ran Concorde at a profit.

        • The lesson from Concorde is that far more people care about low ticket prices than about speed.

          This is really hard to say because no one in the industry is offering a faster product -- everyone flies in the vicinity of 0.80 mach. So yeah, currently people prefer lower ticket prices to speed because they literally cannot buy speed short of going private.

Given the amount of money he made doing that, paying $10K-$15K per hour in the air (2x-3x Gulfstream prices) makes sense. There probably aren't enough people in the overlapping circles of money-is-no-object people and people who still fly scheduled commercial.

    It took several lawsuits to get the supersonic Concorde allowed in just 2 US airports - Dulles and JFK. People didn't want the sonic boom noise and as the article said, congress banned supersonic flight over US soil in 1973. Another problem with the Concorde was that it took a ridiculous amount of fuel to get to supersonic speeds. The plane couldn't carry enough fuel for a transpacific flight. Advancements may fix this, but realize that swapping the Boeing 737 engines to more efficient engines is what stated the entire Boeing crash debacle. (short version: the newer, more efficient engines were larger and didn’t fit under the wing. New mounting pods shifted the new engines forward changing the center of gravity and reducing the stability of the plane resulting in Boeing building the MCAS system and bullying its way through the FAA to avoid complete recertification of the 737 airframe)
    • congress banned supersonic flight over US soil in 1973.

      But this time it's different, a US corporation is planning to do it. Not those pesky French/British.

      • But this time it's different, a US corporation is planning to do it.

        Even corporations though will struggle battling the mighty NIMBY forces of affluent neighborhoods who don't want multiple sonic booms over their homes each day. Flying out of Dulles and JFK requires any aircraft to cross over some of the most affluent counties in the United States.

        Would also add that in the 1970s, the US aerospace industry was on track to introduce their own supersonic transport. Those plans were blown up however by the heavy supersonic restrictions.

        • It seems to be quite easy to take off from JFK and go over water before crossing the speed of sound. Might be a little detour when heading to LA, though, so not sure if it's worth it.
          Dulles is further away to the ocean, but again shouldn't be a real problem for transatlantic flights.

          A lot of big cites are close to the ocean anyways.

        • I'm not saying it wasn't justified. I live hundreds of kilometers from major eastern US/Canada airports and can still hear planes from my bed around 10.30-11pm when they must be heading to Europe. And this is with all windows closed. So of course even noisier airplanes can be a nuisance.

          But still, somehow people in France and the UK were more accepting of the noise. Because the Concorde was their invention probably has something to do with it.

        • I guess you are mixing up sonic boom with super loud.

          A sonic boom is a boom, lasts 2 or 3 seconds, then it is over. And yes, that is super loud, too.

          But super loud in your example means: you are basically looking from behind into the engines. That lasts for minutes: and is _really_ super loud.

          However at that time it was not focused on climb angels and directions to avoid echoing the engines all over the city.

    • Advancements may fix this, but realize that swapping the Boeing 737 engines to more efficient engines is what stated the entire Boeing crash debacle. (short version: the newer, more efficient engines were larger and didn’t fit under the wing.

      Indeed but you're missing the obvious: Energy efficient engines was Boeing's answer to customer demands. This story on the other hand is the customer demand. United isn't stupid. They know that either a) they are making this announcement to bilk investors, or b) they think they have a market for a less efficient design.

      In other news a good friend of mine drives a 5L V8 bi-turbo mercedes. He gets around 1/5 of the fuel economy of my 900cc 3cyl. He happily pays more for wanting that experience. I don't.

        • United isn't stupid.

          Facts not in evidence.

          Don't confuse them giving the middle finger to customers, not giving a shit about maintenance or their staff, and their general customer satisfaction with stupidity. You want evidence: They routinely post yearly earnings per share of $11 ($3bn profit).

          You don't run a profitable business (especially in the airline industry) by being stupid.

    • To clarify the engine problem, new, larger engines were put on existing airplane body designs to save money in the design process. Boeing could have changed the airplane with taller landing gear to accommodate. However Boeing's goal was to minimize all changes so that airports would not need changes to equipment and airlines would not need retraining.

      The 737 issue is a completely different kettle of fish. The problem was the 737 was designed in the 60s before high bypass turbofans, rather than modify the landing gear (which would have been expensive) they just slung new engines too far forward and tried to compensate for the instability with software. The impetus behind this was that Airbus had slung new engines onto the A320 family without having to engineer anything because that design was from the late 70s. The problem with a future SST is economic,

    • Don't get it. Concorde only went supersonic over the Atlantic ocean.
  • I watched a video about 3 other companies last week, I don't think United Airlines deserves the credit that the headline is trying to imply.
  • Even Popular Mechanics is going, Come on, not again! Just give up ok!?.

    This concept [cleantechnica.com] has better chance to succeed than supersonic air travel. The market is too small. Except for the AirForce no one can justify plunking down dollars to chase after supersonic flight

    Even Elon Musk is going, if you are going to burn tons and tons of carbon do it for some realistic goal, like establishing a mars colony or something.

    "TWA Flight 841 has actually had two incidents - in 1974 and 1979. The latter is decidedly less morbid.

    During a flight from JFK International Airport to Minneapolis-Saint Paul International Airport, TWA 841, a Boeing 727, deployed one of its slats while cruising at 39,000 feet. This, as some of you will know, is very bad. Not many of you are likely to know why, however, so permit me to explain..."

  • Hopefully the Boom you just heard was not the plane becoming the world's fastest lawn dart.

    We know where that ended up.

  • It's tempting to AssUme this will fare similarly but Concorde engines were of designs now considered primitive (kudos for pioneering FADEC) and the airframes were built of metal instead of modern composites.

    Dissing a design more than half a hundred years newer based on that fossil is rather silly and poorly informed. In it's time it was glorious, but the old men of that time are dead and the young men of that time are old.

      Not only that, but Concorde was a commercial success. It made a lot of money on the one route it could regularly operate on. So those comparisons are in effect saying the new designs will work out fine.

      On the other hand, the check-in/security/boarding times have all got longer and longer. Particularly security at both ends. It destroys the day, and the following day too.

      That's the real problem to solve.

    Concord's primary market from fifty years ago was people who could not afford to be "out of touch" for the 8-10 hours a plane journey might take. For people for whom "time was money."

    Today, those people can sit in a first-class cabin and stay connected for their entire flight. A billionaire CEO is no longer out of touch while they are in the air - So the "need for speed" is no longer as important as it once was.

    In that market, people will choose something like this over being crammed into a supersonic airliner to save 3 hours.

    • spot on. The advent of satellite internet access has obviated the length of journey disconnecting the traveler from communications with clients. Thus the rush for the ultra lavish A380 suites so the luxury businessman could essentially have his little AF-One experience. The newly proposed configurations from Boom and Aerion(RIP) were nearly the same as Concorde, pencil thin fuselages because the aerodynamics for supersonic flight have not changed in 6 decades. Unless someone figures out how to move superso
  • ...the airline industry was having enough trouble flying SUBsonic without crashing.

    AFAIK, operating planes in supersonic realms involves technical precision and perfection at least an order of magnitude better than subsonic. Which means a cost fact of what, 50x?
