Supersonic Plane Travel Is Closer Than You Thought

Supersonic Plane Travel Is Closer Than You Thought

For many travelers, the words ‘supersonic flight’ conjure up images both futuristic and nostalgic.

Gone are the glory days of the Concorde , the iconic long-nosed jet that transported celebrities and assorted jet-setters across the Atlantic in just a few hours. Beloved for its short transit time— New York to London in just over three hours, going at about twice the speed of sound—the Concorde met its end because of a variety of complications. Firstly, the fact that the jets created a loud sonic boom (the roar that results when an aircraft breaks the sound barrier), and even more importantly, that they were expensive to operate, making it difficult for airlines to turn a profit. By 2003, Concorde was defunct.

But now, two aviation projects are working to overcome those concerns to make supersonic air travel a reality for passengers once more: a private company called Boom Technology and the second, a partnership between NASA and Lockheed Martin. Later this year, both programs will hit a major milestone when they launch test flights of their innovative aircraft for the first time.

Here’s what travelers should know about the supersonic test flights launching in the US in 2024.

A quest for a quiet boom

One major reason why supersonic planes are no longer a facet of modern air travel is the deafening boom the jets create as they cross the sound barrier. Due to the thunderous noise, Concorde was only allowed to fly faster than the speed of sound over water, a regulation still in place for supersonic flights today.

But NASA and Lockheed Martin are endeavoring to find a way to make crossing the sound barrier quieter. NASA’s mission, called Quesst, is to design a jet that creates a noise more like a “sonic thump,” than a roaring boom, according to a NASA release .

NASA and Lockheed just debuted that experimental jet to the public on January 12. Dubbed X-59, the jet is expected to fly 1.4 times faster than the speed of sound—or 925 miles per hour. The aircraft’s innovative design, unique shape, and other technologies are expected to help diminish its sonic boom.

The X59 jet is expected to fly 1.4 times faster than the speed of sound—or 925 miles per hour.

The X-59 jet is expected to fly 1.4 times faster than the speed of sound—or 925 miles per hour.

With the design now complete, the aircraft will undergo a series of ground tests before its first flight. “The aircraft is set to take off for the first time later this year, followed by its first quiet supersonic flight,” NASA says. The first test flights will take place in California , both at Lockheed’s and NASA’s research centers. “Once NASA completes flight tests, the agency will fly the aircraft over several to-be-selected cities across the US, collecting input about the sound the X-59 generates and how people perceive it,” the agency’s release says.

NASA will share its data with regulators and the wider air travel industry. “By demonstrating the possibility of quiet commercial supersonic travel over land, we seek to open new commercial markets for US companies and benefit travelers around the world,” Bob Pearce, associate administrator for aeronautics research at NASA Headquarters in Washington, says in the release.

A supersonic jet with a business-class feel

NASA isn't the only major player working to bring supersonic flight back from the past and into the future of air travel . Boom Supersonic, a private company based in Colorado, aims to bring commercial supersonic flights back to US airlines by 2029. When completed, its passenger aircraft, Overture, is expected to fly at speeds up to Mach 1.7, which is about 1,300 miles per hour—or twice as fast as today’s passenger planes .

At those speeds, passengers can travel from New York to Rome in just five hours (instead of eight), Honolulu to Tokyo in four hours (instead of more than eight), and Zurich to Philadelphia in less than five hours (compared to nine).

Boom’s first test aircraft, called XB-1, is set to take its first test flight in early 2024 at the Mojave Air and Space Port in California. XB-1 is a supersonic demonstrator jet, used to prove Boom’s ability to cross the sound barrier, and not an aircraft that will carry passengers. (Overture, which is designed to carry passengers, isn’t expected to be tested until 2026.)

“In the last 12 months, XB-1 has received its airworthiness certificate from the Federal Aviation Administration, completed an extensive Flight Readiness Review (FRR), and successfully executed a series of integrated ground and taxi tests,” Boom says on its website . So far, the XB-1 has reach speeds of up to 108 miles per hour during taxi tests on the ground. Before the jet can fly, it will need to complete a few more ground tests, including high-speed taxis.

The company says that the Overture aircraft is being designed to meet today’s takeoff and landing noise levels, and will only cross the sound barrier over water. Boom could also possibly leverage NASA’s quiet boom technology in the future, according to a company spokesperson. “When flying over land, Overture can fly significantly faster than subsonic commercial jets—about Mach 0.94, without breaking the sound barrier,” says the Boom spokesperson. “This is about 20% faster than subsonic flight.”

Boom’s first test aircraft, called XB-1, is set to take its first test flight in early 2024 at the Mojave Air and Space Port in California.

Learnings from XB-1’s test flights will be applied to the Overture jet that will carry passengers past the sound barrier. US airlines have already begun placing orders for Boom’s supersonic aircraft, in anticipation of Concorde-like travel becoming mainstream once again.

United Airlines was the first carrier to purchase supersonic planes from Boom, ordering 15 of the Overture jets, set to be delivered in 2029, with an option to buy an additional 35. “Among the many future potential routes for United are Newark to London in just three and a half hours, Newark to Frankfurt in four hours and San Francisco to Tokyo in just six hours,” United said when it announced the purchase.

American Airlines , which ordered up to 20 of the aircraft with an option to buy an additional 40, said its potential supersonic routes could include “ Miami to London in just under five hours and Los Angeles to Honolulu in three hours are among the many possibilities.”

Of course, fares will be left up to the airlines to set; however, Boom CEO Blake Scholl has said that the planes are designed to compete with current international business-class ticket prices, starting around $5,000.

Inside, the planes will have a more exclusive atmosphere compared to current planes flying international routes, carrying just 64 to 80 passengers. Boom is designing its supersonic plane cabin to compete with current airlines’ top business-class products . Some of the cabin features could include large personal windows, direct aisle access, dedicated underseat storage , and a first-class, lie-flat experience .

How will supersonic air travel impact travelers?

The modern revival of supersonic air travel has the potential to create a more sustainable way to fly. Not only could the sonic booms be quieter (thus reducing the negative effects aircraft noise can have on wildlife), but the plane’s carbon footprints could also be drastically reduced. Boom’s planes will be able to run entirely on sustainable aviation fuel , meaning the flights could emit a net-zero carbon output.

While many of us may never get to experience the golden age of flying , supersonic jets could usher in a new era of luxe flying—for when it comes to travel, time truly is our most precious commodity. For many customers “Concorde delivered efficiency, effectiveness, comfort, and the ability to do in two days what would otherwise take four,” Mike Bannister, former chief Concorde pilot for British Airways said in a Boom release in 2020. Supersonic flight was especially appealing to business travelers , who had the ability to make a day trip out of a long-haul transatlantic trip. “They could travel from London to New York and back in a single day and still have time to do business upon final landing," he said.

The short travel times can also help significantly reduce the effects of jet lag , according to former Concorde passengers and pilots. “In crossing the Atlantic from London to New York in three hours and twenty minutes, we endured no jet lag, arrived on time, earlier than we left, and with very happy customers,” Bannister said. (This becomes especially true if you can take a day trip across time zones and retire for the night in your own bed.)

We Don’t Need Supersonic Travel—in the “New Normal,” We Should Slow Down

By Bill McKibben

Boom Supersonic's Overture passenger jet

Subscribers to The Climate Crisis newsletter received this piece in their in-boxes. Sign up to receive future installments.

An interesting question: Did the pandemic break something in the heedless momentum of human acceleration, or are we really going straight back to normal?

An interesting test case: United Airlines’ announcement that it will buy fifteen supersonic jets, which would allow business travellers to fly from San Francisco to Tokyo in six hours, and take “day trips” across the Atlantic.

Surely, we don’t want this. In part, of course, because it’s climate-insane. Supersonic planes, as Kate Aronoff points out , emit five to seven times as much carbon per passenger as conventional jetliners. United’s statement that the planes, which could be in operation by the end of the decade, will be “net zero from day one” is perhaps the best example yet of what an empty pledge “net zero” is turning out to be. Among other issues, the planned fleet of planes could use up twice the European Union’s supply of “sustainable jet fuel.” (By the way, if you want an example of creative greenwashing, here’s a piece making a case that more private jet travel may be “beneficial” for the climate. “Saying too loudly it’s better to have a few wealthy folks and their shiny jets instead of more widebody airliners arriving with budget travelers doesn’t necessarily go over well,” the author writes, adding that some companies have introduced “jet-sharing programs” so that “private fliers can carpool.”)

But let’s talk about something more than emissions. If we’re going to take climate change seriously, it also needs to come with a new aesthetic. We have to start seeing wind turbines on the horizon as kinetic art, not blight, for instance. And we might want to rethink what travel means, something that our pandemic year should have helped us with. At this point, it’s clear that you can conduct a lot of business remotely. What that means is not that we need to stay at home forever but that we could learn to travel slowly , precisely because we can e-mail the whole way, and because, as Zoom insists , people are learning to use it at thirty thousand feet. (Turn off your mic and use the chat, people.) Also, there’s Slack.

More exciting than United’s supersonic order was the news that, as early as 2025, an outfit called Hybrid Air Vehicles may be offering regularly scheduled blimp service between cities such as Seattle and Vancouver, or Barcelona and Mallorca, or Liverpool and Belfast. According to the company, dirigible travel will emit ninety per cent less carbon dioxide per passenger mile than a standard airplane—and, by 2030, an all-electric version may eliminate emissions entirely. But I think the experience will be the thing: with no need for a runway (and no jet-engine noise), the blimps could land near the center of cities. And blimp passengers, instead of strapping themselves into a metal cylinder with tiny windows and enduring a cramped ride, will have huge windows to gaze out of and plenty of room to move around. Yes, there will be luxury options for the rich—that feature of our world won’t disappear. But these options do sound nice: a Swedish firm has already ordered a dirigible outfitted with deluxe cabins for trips over the North Pole. I’d save for years to do that once.

So far, the best descriptions of what this new world could be like come from Kim Stanley Robinson , a science-fiction author who specializes in depicting the kinds of delights that a world that took our predicament seriously might produce. Travel by blimp has featured prominently in several of his books, most recently the wonderful “ The Ministry for the Future .” In the novel, he writes that takeoff “felt strange, lofting up over the bay, bouncing a little on the wind, not like a jet, not like a helicopter. Strange but interesting. Dynamic lift; the electric motors, on sidecars up the sides of the bag, could get them to about two hundred kilometers an hour over the land, depending on the winds.” In Robinson’s book, the travellers stay aloft for days, their pilot following animals or dropping down to see the snouts of glaciers. And here’s the thing: the passengers can keep working if they need to.

As with the air, so the sea. In the early stages of Robinson’s new world, ships are outfitted with solar panels that run electric motors. But soon people are building clipper ships with six sails, each one made of photovoltaic material, so that it can capture both wind and sun power. Because it’s possible to keep working on board, even the President of the Ministry of the Future, arguably the most important person on the planet, can take one, “winds pushing and pulling them, the sun, the waves. The glorious glide, crest to trough, trough to crest, long rollers of mid-ocean.” This is a world worth wanting, one that manages to be both slimmer and far more elegant.

Passing the Mic

As the New Yorker investigative reporter Jane Mayer wrote in her account of the Koch family’s influence, “ Dark Money ,” this money is often given in order to further the Kochs’ libertarian political approach, which has included a stiff dose of delay and obstruction in addressing climate change. Mayer quoted a Koch official as saying that the family’s “investment” in education had created a valuable “talent pipeline.” Assuming that, on average, thousands of scholars taught hundreds of students per year, the official said, the Kochs and their cohort could influence the thinking of millions of young Americans annually. “This cycle constantly repeats itself,” he noted, “and you can see the multiplier effect it’s had on our network since 2008.” Last week, a group called UnKoch My Campus, which is part of the nonprofit Essential Information, released a searchable database of recent donations that the Charles Koch Foundation has made to universities. I asked Jasmine Banks, the executive director of UnKoch My Campus, to explain; the interview has been edited for length and clarity.

Money from the Koch foundations gets put to many purposes—do you think that there’s a significant amount that ends up funding climate denial on campuses?

The money can be difficult to track once it makes its way to schools. And the connection may not always be clear at first. With George Washington University and the Regulatory Studies Center, there’s a direct line . In other places, such as George Mason University, which has received nearly a hundred and eighty million dollars from Koch foundations since 2005, the connection is less transparent. The school itself isn’t putting out climate-denial data, but it produces lawyers, lobbyists, politicians, and judges who could enact a climate-denial agenda.

How are students responding to news of this funding? And what about faculty?

We have student and staff organizers on the ground who have been pushing back against Koch money for a while, so to see the numbers laid out plainly at their schools and others reminds them what they have been fighting for. We've found that, when it comes to faculty, many are tentative about speaking out because of potential repercussions.

Many people might say, ‘It’s their money, they can do what they want with it.’ How do you explain to them why you think it’s dangerous?

The money itself isn’t dangerous—it’s the strings and conditions attached to it where we start to see the harm. When donations dictate what curriculum or textbooks are being taught, what faculty is hired or fired, or exert influence over school fellowships, then it becomes a matter of academic freedom.

Climate School

Utilities are increasingly pairing wind and solar power, usually with a battery to store power. Power magazine quotes an analyst explaining why: “The cost for projects involving solar, wind, and storage have certainly come down in recent years. Storage in particular has become much more competitive. Two to three years ago, the costs were simply too high and didn’t make economic sense. But while the price tag has gotten smaller, the economic feasibility of projects that combine renewables with storage remains jurisdictionally dependent. As the old real-estate adage goes, ‘location, location, location.’ ”

Ella Nilsen at Vox offers a detailed analysis of a problem that I laid out a few weeks ago: until there’s a better national network of charging stations, it may be hard to persuade more buyers to opt for electric vehicles. She quotes an expert, saying, “In San Francisco, there’s a huge congestion problem, and there are simply not enough plugs for EVs in that metro area. There is congestion in areas where EV demand has flourished. If we don’t get going on this, we will have roadblocks, especially for longer trips.”

Campaigners at Fossil Free Netherlands—who were involved in the recent case that led a Dutch court to demand that Royal Dutch Shell cut emissions forty-five per cent, and who won a ban on fossil-fuel ads in Amsterdam’s metro stations—signed their name to a report detailing the ways that “social tipping points” could speed climate action. The authors say that governments should push for new technology, but that this will happen faster and mean more if lawmakers eliminate “fossil subsidies, and invest that money to help citizens, businesses, and organizations become more sustainable.” Meanwhile, that Dutch court ruling continues to spark insightful analysis. The international human-rights lawyer Tessa Khan, writing in the Guardian , reckons that “it is hard to overstate the consequences of a decision that is already being hailed as a turning point for big oil. Given the replicability of the arguments and the international standards and common facts that comprise the basis of the case, it will inspire a wave of similar actions around the world.”

Rebecca Leber offers some of her always illuminating reporting , this time singling out the Permian Basin in Texas as the place that may tell the story about the future of oil and gas in the United States. She writes that relying on state regulators is unlikely to get much done: authorities in Texas have rubber-stamped thirty-five thousand requests to flare heat-trapping methane from wells, without issuing a single denial.

A new report from the N.G.O. Amazon Watch details the holdings of the three biggest asset managers— BlackRock , State Street, and Vanguard—in oil companies that operate in the world’s largest rain forest. The total of those investments is forty-six billion dollars, and, the report says, the oil companies are often linked to human-rights abuses and deforestation in the region.

The Wall Street Journal has noticed that a nationwide “battle brews” over bans on connecting gas to new home construction, writing that this has “the potential to reshape the future of the utility industry, and demand for natural gas.” Another advance in that fight came last week, when activists in the town of Brookline, Massachusetts, persuaded the annual town meeting to make new construction permits conditional on an agreement to go fossil-free.

A new study in the journal Nature Climate Change states that thirty-seven per cent of heat-related deaths around the world are attributable to the excess heat that attends the climate crisis. As John Schwartz summarizes , in the Times , “Climate change has added to overall mortality from all causes by as much as 5 percent in some parts of the world, the authors found; they detected increased mortality from climate-boosted heat on every inhabited continent.”

Over the years, researchers have learned that wolves play a key role in restoring ecosystems, by reining in prey, such as deer, that can overbrowse trees and shrubs. A new study has found that wolves also save human lives—by reducing deer numbers, they cut fatal car collisions.

Given the subject of today’s newsletter, I can perhaps be forgiven for admitting a fondness for the 5th Dimension and its treatment of lighter-than-air travel. For good measure, here is Hugh Masekela’s version .

Breaking The Sound Barrier: The Science Of Supersonic Flight

Jet producing a sonic boom

Although few people ever get the chance to travel at the speed of sound, it is an alluring flight goal and an impressive technological feat. Though average people have flown at high speeds on airplanes, supersonic flight is almost exclusively reserved for fighter pilots in  superpowered jets at speeds far in excess of Mach 1. That hasn't always been the case, though, with commercial airliners that could break the sound barrier having operated in the not-so-distant past.

But what does it take to break the sound barrier and travel faster than the speed of sound? It is a process that involves unique challenges and scientific concepts that are simply not part of the flying experience most people are familiar with. Perfecting supersonic flight was a painstaking process and there is a long history behind it that began more than half a century ago, with the first aircraft capable of traveling at more than Mach 1.

Here we will look at exactly what flying faster than the speed of sound means, and how it is made possible.

What is supersonic flight?

Perhaps the most important question when discussing supersonic flight is understanding exactly what the term means. Essentially, supersonic flight means any type of flight where an aircraft travels faster than the speed of sound. NASA's Edward Haering , a researcher studying sonic booms, describes it as cruising "faster than the sound waves can move out of the way." This is often referred to as Mach 1 and is calculated as the velocity at which sound waves travel through the air. So an aircraft that is capable of traveling at Mach 1 should reach its destination simultaneously with a sound wave, or any other kind of vibration, leaving from the exact same point.

However, there is no set speed of sound. Like the speed of light, the maximum velocity of sound waves depends on a variety of external factors, including the temperature and pressure of the air. At sea level with a temperature of 15°C (59°F), the speed of sound is around 760 miles per hour. Yet, this can fluctuate significantly, with the speed of sound slowing down the higher up you go as a result of a drop in temperature. That's because molecules, which carry the vibrations through the air or other materials, move more slowly at colder temperatures as they have less energy. For that reason, the Mach 1 is calculated as a ratio so that it changes according to the conditions with which the aircraft is met.

The difference with hypersonic flight

Broadly speaking, there are four different classifications for flights in terms of speed. These are used primarily to determine the type of flight depending on the speed the aircraft is traveling. Subsonic refers to any aircraft that is moving slower than Mach 1, meaning it is below the speed of sound. Transonic describes aircraft that are traveling at the speed of sound, usually within a range of between Mach 0.8 and 1.2. Meanwhile, supersonic flight is any flight that is faster than Mach 1.

The fourth classification, hypersonic , is a much faster type of flight where an aircraft passes through the atmosphere at speeds greater than Mach 5. That means they will generally need to be going faster than 3,000 miles per hour to be considered hypersonic. Aircraft that can travel at speeds of Mach 5 or greater are subjected to entirely different conditions than other planes, as they experience a huge amount of heat. According to the National Air and Space Museum, the massive amounts of friction that aircraft are subjected to as the air passes over them during hypersonic flight is the main challenge to overcome in designing functional vehicles.

What happens when something breaks the speed of sound?

Reaching and surpassing the speed of sound has a noticeable effect. It doesn't matter the size or shape of the object; once it passes the sound barrier, it will produce a sonic boom. This shock wave sounds like an explosion or a clap of thunder and is powerful enough to cause structural damage to nearby buildings, measuring up to 110 decibels at its peak. Sonic booms are created because the object moves faster than the sound waves it produces.

As the supersonic aircraft moves through the air, sound waves emanate it and move out in all directions. While accelerating, the sound waves radiating from the front of the aircraft begin to compress together and eventually become one large shock wave due to the pressure. A sonic boom isn't a single release, though, with the wave moving alongside the supersonic aircraft as a cone of sound.

A good example of this is the crack that comes from a whip. This sound isn't caused by the material of the whip coming into contact with itself but rather the loop moving along the whip at ever-increasing speed until it eventually breaks the sound barrier causing the loud cracking sound. Essentially, a whip crack is actually a small sonic boom as part of the whip travels faster than the speed of sound.

Physics of flight

‌Before understanding exactly how supersonic flight is possible, it helps to have a good idea of how normal subsonic flight works. The physics of flight involves four forces acting upon the aircraft in the form of lift, weight, thrust, and drag. Weight is a result of gravity, and drag is a product of air friction as the aircraft moves through the air. To overcome these two forces, an aircraft must produce enough thrust and lift to get off the ground and remain in the air.

The engines of an aircraft provide the thrust. These components burn fuel and spin turbines, pushing air out to propel the aircraft forward, with more thrust needed at higher speeds as drag increases in proportion to the velocity of air flowing over the structure. At the same time, the shape of the wings forces the air to flow in a specific way both under and over them. This creates a pressure differential on the wings, effectively forcing the aircraft to move up. The angle of attack of a wing can produce more or less lift depending on the needs of the aircraft, allowing it to climb or maintain altitude at different speeds.

A stall can occur during flight when the airflow over the wings is disrupted. This can happen because the plane is moving too slowly or the wing's angle of attack is too high. In either case, the wings can no longer generate sufficient lift as the airflow becomes chaotic.

Physics of supersonic flight

Many of the physics concepts that are in play during normal flight also apply to an aircraft going faster than the speed of sound. However, there are also other properties that need to be considered. The primary concern for a supersonic aircraft is drag. At supersonic speeds, air molecules cannot be pushed out of the way quickly enough, which creates substantially more air friction than is the case with subsonic flight.

This additional drag poses a number of problems and means that supersonic aircraft have to have different designs to typical airliners. They will typically be thin and narrow, improving the way the jet or plane is able to smoothly move through the air, lowering drag by reducing the amount of air friction. Supersonic aircraft often appear as sleek triangular shapes for this purpose.

They also have to be able to withstand high temperatures, with the air friction causing the body of the aircraft to heat up dramatically. Standard materials used by the commercial aviation industry may not be able to cope with these temperature extremes, requiring strong and more durable alloys. Finally, engines need to be far more powerful to provide the necessary thrust and to be able to fly at the higher altitudes necessary to help reduce air friction. However, design choices and components also make flying at subsonic and transonic speeds more difficult.

The history of supersonic flight

Supersonic flight had its beginnings in the 1940s. Partly based on research by a British project to create an aircraft that could break the sound barrier, Bell Aircraft and various U.S. government organizations collaborated to produce the Bell X-1. Essentially, its engineers modeled it on the shape of a bullet, knowing that these objects could easily break the sound barrier. After extensive testing, the rocket-powered aircraft made its first supersonic flight at the hands ofvU.S. pilot Charles "Chuck" Yeager in 1947, reaching a speed of Mach 1.06. This demonstrated not only that air travel at faster than the speed of sound was possible but that it could also be done in a controlled manner.

After this breakthrough, various militaries around the world began to design supersonic fighter jets. By the early 1950s, both the U.S. military and Soviet Union's had developed fighter jets that were capable of supersonic speed. These included the MiG-19 and the F-100D Super Sabre, although many other models would be developed over the years. In fact, most modern fighters can now travel at speeds significantly higher than Mach 1 , such as the F-35 and the Eurofighter Typhoon. The fastest aircraft in history is the Lockheed SR-71 Blackbird, which had a top speed of Mach 3.2.

In terms of commercial aircraft, there have only been two main airliners that could travel at faster than the speed of sound. The Russian-made Tupolev Tu-144 began operating in 1975 but retired just a few years later in 1978. Meanwhile, the French-British Concorde entered service in 1976 and continued to fly passengers until 2003 when it was officially retired. The Concorde had a supercruise speed of Mach 2.04.

Dangers of supersonic flight

‌Although supersonic aircraft are impressive from a technological standpoint, they are also more susceptible to certain dangers than traditional means of air travel. The biggest challenge is constructing a vehicle that is strong enough for supersonic flight. Traveling faster than the speed of sound puts an enormous amount of stress on the structure of an aircraft due to both the extreme forces acting upon it and the sudden changes in pressure associated with sonic booms. Air friction is also a danger, as it causes thermal stress as parts heat up and rapidly expand. Extreme vibrations during acceleration and braking is also common, putting further strain on an aircraft's components and frame.

The dangers of supersonic flight are not just confined to the aircraft either. The higher speeds mean pilots have less time to react to issues or troubleshoot potential problems. That could, in turn, make catastrophic incidents more devastating if a supersonic aircraft was near populated areas while encountering problems. Sonic booms are also destructive and are capable of causing structural damage to buildings on the ground or smashing windows. There are also concerns about possible hearing damage to those who might experience a sonic boom and general noise pollution.

Another major danger with supersonic aircraft is that they consume much more fuel than their subsonic counterparts. To overcome the increased drag created by traveling at these high speeds, engines need more power and a higher fuel level. These types of aircraft are also typically heavier because they need to be stronger and operate at higher altitudes – both factors that reduce fuel efficiency. Ultimately, supersonic flight creates more emissions than other forms of flight.

Future of supersonic flight

The world's only long-term supersonic airliner was the Concorde, which was operated by Air France and British Airways from 1976 until 2003. Primarily used for transatlantic flights, it could travel at a cruise speed of Mach 2 or roughly 1,350 miles per hour. However, the Concorde was retired due to several factors, chief among them being that its high operating costs made it unaffordable to most passengers. The problems associated with sonic booms also meant that they couldn't be flown at supersonic speeds over populated areas so could only operate on specific flight paths.

The dangers of supersonic flight and the associated costs have made it prohibitive to operate aircraft that can travel faster than the speed of sound in a commercial capacity. Yet, that hasn't stopped companies from investigating the possibility of bringing back supersonic airliners. Both American Airlines and United Airlines have placed orders for supersonic aircraft from Boom Supersonic. It is possible that these new aircraft could be operational by 2029.

A European organization known as Destinus is also proposing a hydrogen-powered flight that will be able to travel at Mach 5. The company has already completed several test flights and hopes to have a supersonic hydrogen-powered flight in 2024. Concepts for potential hypersonic aircraft are also in development, which could dramatically cut flight times around the world.

Making sonic booms less powerful could be possible

Of course, the major drawback of supersonic flight is that any object breaking the sound barrier produces a sonic boom. As these are potentially dangerous, most governments ban supersonic flights over populated areas as they can distress humans and animals or cause damage to buildings. While it is impossible to completely do away with sonic booms, reducing their effect could make supersonic flight a much more enticing and viable prospect.

One organization working to make sonic booms quieter is NASA . Its X-59 Quiet SuperSonic Technology aircraft is intended to create a sonic thump rather than a boom, by manipulating the sound waves produced by the aircraft. A scale model has shown promising results, with wind tunnel tests matching up with the theoretical predictions. NASA hopes that, in time, its research could make supersonic flight over the United States possible.

Boom Supersonic is also in trials for its own solution, Overture aircraft, which aims to allow supersonic flight at speeds of Mach 1.7. Using what it calls the Symphony engine, the Overture is being designed to be quieter than any other supersonic aircraft. The company currently has many experts working for it, including engineers who helped design jet fighters such as the F-22 and F-35.

Dyson Supersonic hair dryer

The high-demand hair dryer performs fast drying and controlled styling to help increase smoothness by 75%, increase shine by up to 132% and decrease frizz and flyaways by up to 61%, Dyson says. It comes with five attachments, provides heat control for fast drying with no heat damage and is powered by Dyson digital motor V9.

“I’d wanted one of these Rolls-Royces of hair dryers for years but could never justify paying many times the cost of standard ones. I saw another ad that caught my eye late in 2022 and it dawned on me I could pool together gift cards I had received for Christmas and my late December birthday – plus a rare 20 percent discount. I bought the hair dryer the next day and it is worth every dollar. It comes with a handful of accessories like a diffuser and concentrator. The best feature: I can straighten my thick, curly hair in half the time as my standard Revlon hair dryer. I can get it straight in less than 15 minutes. In addition to saving time, I’m now straightening my hair probably four times more often. Even in the summertime. That hair dryer is that much of a difference maker.” -- Kristen Davis of
