These Next-Gen Supersonic Jets Want to Replace the Concorde. Will They Ever Take Off?

Skeptics think not, but a core of true believers are inching forward with new designs and test flights.

By J. George Forant 14/06/2024

To dig into the state of supersonic flight these days is to invite an unlikely conversation about cell phones. Three out of five experts in the field compared the smartphone of 20 years ago with a future generation of jets that hope to blow past Mach 1.

“Think of the original iPhone. In those early days, it made huge leaps every year. That’s where we are with supersonic,” says Blake Scholl, CEO of Boom. “Tech advances in S-curves. Products go through periods of slow development, then rapid improvement, then level off again to incremental gains.”

The Concorde, the world’s only commercial supersonic jet, was the big, clunky plastic phone that the very wealthy first had in their cars, while the new breed of supersonic jet is a flip phone with a keyboard that, according to supersonic’s believers, will eventually morph into the sleek, multifunction supercomputer that has become so affordable that it’s available to almost everyone.

“It’s taken longer than we would’ve hoped, but there will absolutely be supersonic flight,” says Vik Kachoria, the CEO of Spike Aviation. “We think supersonic will offer a lot of value and will be very useful.”

Not everyone shares his certitude.

“If you go back and look it up, starting from the ‘90s, proponents of supersonic flight say it is always 10 years away,” says Brian Foley, a business aviation industry consultant. “Why 10 years? Probably because it’s a number that’s not too distant, but far enough that when the time comes, no one will remember all the promises you made and failed to deliver on.”

One hopeful, Aerion, which counted Boeing and Lockheed Martin as investors, shuttered in 2021 after nearly 20 years of planning for its next-generation AS2 supersonic business jet. If any private company had the potential create a new commercial supersonic reality, it seemed to be Aerion. The backers invested billions and hired top aerospace engineers to work on the minutia of flight beyond Mach 1.0, or 1234 kph.

Then, out of the blue, the company shut down because it couldn’t secure long-term investors who believed in supersonic’s potential. “They had put together amazing talent,” said aviation consultant Rollie Vincent, who did some work for Aerion, shortly after the closure. “The number of PhDs per square foot was off the charts,” he said. “But they weren’t building things. They were trying to refine design and purify aerodynamics. At some point, everybody, including investors, want to see real parts.”

Aerion’s AS2 was the poster child of a potentially successful supersonic jet. After 20 years, the company abruptly folded.

Boom, now leading a handful of private supersonic aircraft developers, seemed to realise early that it needed hardware to demonstrate its progress. The company launched its XB-1 demonstrator jet on March 22. Its initial flight topped out at less than 240 knots, but for the first time since the Concorde, a non-military plane built for supersonic speed executed a successful flight. If future test flights progress as projected, the XB-1 could make a run at the sound barrier within a year. And the company’s 150,000-square-foot production facility in Greensboro, N.C., is on schedule to open in late ‘24.

Not far behind, NASA’s X-59 experimental craft should make its first flight later this year. The jet, a product of the QueSST project, represents the government’s attempt to reduce the sonic boom, a key development for supersonic’s commercial future, since it’s illegal to break the sound barrier over land in the U.S. and most other countries.

“The key to lowering the boom is in shaping the airplane and the wing, smoothing them out so the shock waves don’t combine,” says Dave Richwine, deputy project manager for technology on the X-59. “NASA is working at a fundamental level and, hopefully, the industry will bring it all together.”

There are signs that approach is working. Spike has absorbed much of NASA’s work while modifying and applying the theories to a larger craft, its 12- to 18-seat business jet called the Diplomat, which won’t launch until at least 2026. Like the X-59, it aims to reduce the boom by manipulating and flattening the sonic waves so they’re directed upwards and largely cancel each other out. The goal is a sonic “thump” or a ground-level sound of roughly 75 decibels perceived, akin to a closing car door.

Exosonic, which is developing unmanned supersonic drones for military training and a 70-seat passenger jet, expresses a similar goal on sound, and is part of the group rallying to change the current law. Instead of a speed limit, builders want a sound limit, so it doesn’t matter how fast a plane flies, so long as it doesn’t rattle the windows of the houses it passes over.

Boom is less preoccupied with noise. Scholl says at some point, a standard will be issued and Boom will meet it. For now, the company plans to address the issue by only going supersonic over the ocean. Over land its planes, says Scholl, will operate 20 percent faster than current commercial jets.

In theory, Boom’s XB-1 will eventually lead to the Overture, the 64- to 80-seat commercial aircraft the company plans to build once it dials in the technology. American, Japan Air, and United have all put in non-refundable preorders of Overtures, and Scholl hopes the plane will be flying with passengers by 2030.

“We’re very engaged with the FAA and we’ve already received our G1 certification,” Scholl explains. “It’s a long list of boxes we have to check, as it should be, but we’re locked in on the needs and all we have to do is meet them.”

All these supersonic projects feature a modified delta wing and a long, tapered nose that gives the craft a more futuristic, streamlined profile than the Concorde. Aesthetically, the designs are attractive, but they also make it impossible for pilots to see, a problem solved by a system of cameras mounted on the exterior. The XB-1 includes an augmented reality overlay with guidance for the pilots.

Facing critics and shortfall in development funds, Boom CEO Blake Scholl remains a cheerleader for supersonic’s potential.

Spike, which has a longer development timeline, eliminated almost all the windows on the body, replacing them with hi-definition flat screens that run the length of the cabin, on which they can project the exterior view—or a movie or “anything you can put on a computer screen,” says Kachoria.

The Spike chief executive compares the Diplomat to a Gulfstream, with a customisable interior and the option of plush, oversized seats, and Exosonic too plans a business jet version, with three suites, executive seating, and full-recline chairs. Across the supersonic category, weight limitations will reduce the capacity for the kinds of comforts found in typical first-class service, but other considerations will, presumably, make up for any lack of poshness and interior space. “Instead of getting upgraded to business class, someone might get upgraded to supersonic,” says Kachoria. “You won’t have fancy plates, but you’ll arrive at your destination in half the time.”

Foley, who did market research on supersonic jets when he was employed at Dassault Falcon and has worked with Spike, remains skeptical. He forecasts a market of about 300 jets for private owners, or about 30 planes a year for 10 years: “Is that even enough for an engine manufacturer to participate?”

Apparently not. When Aerion shut down, GE Aerospace halted three years of development of the Affinity supersonic engine designed to power Aerion’s AS2. GE, along with major engine builders Pratt & Whitney, Rolls-Royce, Honeywell Aerospace and Safran all passed on developing an engine for Boom, according to AIN.

That left the company with no option but to form an alliance that included Florida Turbine Technologies, GE Additive and StandardAero to invent a propulsion solution, an engine called the Symphony.

“Designing an engine is no easy task, especially from scratch, and it’s potentially a multibillion-dollar exercise beyond designing the plane,” Foley told Robb Report a year ago.

Sustainability remains a concern for observers. The Concorde burned four times as much fuel as the 747.

Despite that, Boom has built the XB-1 and taken it to the sky. “The technology and supply chain exist,” says Scholl. “There’s no fundamental new science—every key technology in this airplane has already flown before.”

In early 2021, Subaru, Mitsubishi Heavy Industries, and several other companies formed Japan Supersonic Research with a goal of having an SST passenger jet by 2030. They partnered with the Japan Aerospace Exploration Agency and have access to JAXA research going back to 1997. Shigeya Watanabe, deputy director, recently told Aero Society it was working on improving current technologies as well as developing more sustainable propulsion technologies.

Sustainability was a non-issue when the Concorde first took off in 1969. It burned four times more fuel than a 747 on a Paris-New York flight. Fifty-five years later, it’s now a core challenge for aviation, especially supersonic aircraft. Environmental scientists Anastasia Kharina and Tim MacDonald wrote in a study for the International Council on Clean Transportation that “commercial SSTs could be three times as fuel intensive per passenger as comparable subsonic aircraft.”

Spike Aerospace is considering hydrogen power to align with sustainability initiatives in commercial aviation.

Boom and Exosonic hope to solve the green issue by designing their engines to run on 100-percent sustainable aviation fuel (SAF) while Spike is exploring electric and hydrogen. “The technology for design is so much faster now,” says Kachoria in discussing the engineering challenges. “We can make modifications and see the result onscreen in seconds. They built the Concorde with slide rules and drafting paper and did 10 total iterations. We can do 1,000 simulations in a few hours.”

Kachoria sees supersonic’s potential upside as 900 or more planes over 20 years going to a mix of high-net-worth individuals, fractional leasing services, and airlines. Scholl is even more bullish. “Our ultimate goal is to have supersonic flights on all routes for all passengers,” he says. “These planes will create their own need. As soon as people see others crossing the Pacific in four hours, they’ll say, ‘Why are we sitting in this metal tube for so long when we don’t have to?’”

If Boom and the other supersonic builders succeed, how long will it be before someone is asking a similar question about their jets? Destinus and Hermeus are also aviation start-ups, and they’re developing hypersonic jets that will travel at up to five times the speed of sound.

Lack of interest from aircraft engine manufacturers has forced Boom to develop its own engine.

Pipe dreams or the birth of a new era in flight? The outcome could depend, as Aerion found out, on whether the manufacturers can find the start-up funds, amounting to many billions, for a viable niche in commercial and business aviation. “Never say never,” says analyst Foley. “But these things tend to move at the speed of money, and investors don’t seem to have the risk appetite.”

Omega Just Unveiled 9 Watches in Its New Constellation Observatory Collection

The line-up shows up a bevy of metals and colours, too, as well as two new calibres.

By Nicole Hoey 31/03/2026

Omega’s latest watch is in a universe of its own.

The Swiss watchmaker just unveiled its new Constellation Observatory Collection today, the next step in its Constellation lineage and the first two-hand hour and minute timepieces to ever earn Master Chronometer certification. And if you were paying attention to any of the dazzling watches spotted at the Oscars this year, you would’ve caught a glimpse of the new line already: Sinners star Delroy Lindo rocked one of the models on the Academy Awards red carpet, giving us a pre-release preview of the collection.

Developed at Omega’s new Laboratoire de Précision (its chronometer testing lab open to all brands), the collection houses a set of nine 39.4 mm watches. The watches underwent 25 days of scrutiny there, analysed via a new acoustic testing method that recorded every sound emitted from the timepiece to track irregularities, temperature sensitivities, and more in the name of all things precision. (Details such as water resistance and power reserve are also thoroughly examined.) This meticulous process is all in the name of snagging that Master Chronometer label, meaning that the timepiece is highly accurate and surpasses the threshold for ultra-high performance. The Constellation Observatory Collection has now changed the game, though, thanks to its lack of a seconds hand.

“Until now, precision certification has required a seconds hand,” Raynald Aeschlimann, president and CEO of OMEGA, said in a press statement. “The development of a new acoustic testing methodology has made that requirement obsolete. It is this breakthrough that has enabled us to present the Constellation Observatory, the first two-hand watch to achieve Master Chronometer certification.”

In addition to notching its place in history, the collection also debuted a new pair of movements: the Calibre 8915 and the Calibre 8914, each perched on a skeletonised rotor base. The former’s Grand Luxe iteration will appear on the 950 Platinum-Gold model in the collection, which offers up that base in 18-karat Sedna Gold alongside a Constellation medallion in 18-karat white gold with an Observatory dome done in white opal enamel surrounded by stars. The second Calibre 8915, the Luxe, will find its home on the other precious-metal models in the line, either made with the brand’s 18-karat Sedna, Moonshine, or Canopus gold seen across the case, the hand-guilloché dial, and, of course, the movement itself. (Lindo chose to rock the Moonshine Gold on Moonshine Gold iteration, priced at approximately $86,000, for Sinners‘s big night at the Oscars.) As for the Calibre 8914, it can be found in the collection’s four steel models.

Each model is a callback to myriad design features on past Omega models. That two-hand dial, for one, comes from the 1948 Centenary (the brand’s first chronometer-certified automatic wristwatch), while the pie-pan dial (seen in various blue, green, and golden hues throughout the line) and that Constellation medallion caseback both appear on watches from 1952. The star adorning the space above 6 o’clock also harks back to 1950s timepieces from Omega. And to finish off the look, you can opt for alligator straps in a variety of colours, or perhaps a gold iteration to match the precious-metal models; the brick-like pattern on the 18-karat Moonshine bracelet was also inspired by Omega watches from the ’50s.

We’ll have to keep our eyes peeled for any other Constellation Observatory timepieces (or any other unreleased models from the brand) at the rest of the star-studded events headed our way this year—perhaps the Met Gala?

Inside Loro Piana’s First Sydney Boutique

A first Australian address brings the Italian house’s textile-led approach to retail full circle.

By Horacio Silva 26/03/2026

On the fourth floor of Westfield Sydney, near the Castlereagh and Market Street entrance—in the space formerly occupied by Chanel—Loro Piana has opened its first Australian boutique. It is a significant address change for that corner of the mall, and a meaningful one for the Italian house, which has sourced Australian merino wool for decades but until now had no retail presence here.

The facade is understated—creamy, tactile, more about texture than theatre. Inside, the store unfolds across a single, expansive level divided into distinct men’s and women’s wings. The separation is clear without being heavy-handed: womenswear leads from soft accessories and leather goods into ready-to-wear, while menswear occupies its own assured territory, with tailoring and outerwear given proper breathing room. Footwear (supple loafers, luxurious slides, pared-back sneakers) is particularly strong, and the sunglasses are a quiet standout: mineral-toned frames with a disciplined elegance that feels entirely of the house.

That same restraint carries into the interiors, where the surfaces do much of the talking. Walls are wrapped in the company’s own linen and cashmere; carpets are custom, dense underfoot, softening the acoustics and the pace. Oak and carabottino wood add warmth without fuss; marble accents introduce a cool counterpoint. The effect is a composed space calibrated around material, proportion and restraint.

The Spring 2026 collection now in store underscores that sensibility. Silhouettes are elongated and fluid; cashmere, silk and featherweight merino move in sandy neutrals, creams and muddied earth tones, with flashes of marigold and pale turquoise breaking the calm. Tailoring is softly structured and projects confidence without aggression. Leather goods arrive in buttery skins that feel almost pre-lived, as though time has already worked its magic.

What distinguishes Loro Piana, particularly in a market that has grown noisier by the season, is its refusal to perform luxury in an obvious register. There are no oversized insignias telegraphing allegiance. Instead, the status is encoded in fibre count, in hand-feel, in how a coat hangs from the shoulder. It assumes the wearer knows and, crucially, does not need to announce it.

Sydney’s luxury landscape has matured in recent years; global houses no longer test the waters but commit to them. Yet Loro Piana’s arrival feels different. It is not trend-driven expansion but material logic. For a country whose sheep stations have long contributed to the house’s fabric story, this boutique reads almost as a thank-you note written in cashmere.

This Stylish, Water-Resistant Dopp Kit Might Be the Last One You Ever Buy

Patricks’s limited-edition wash bag is designed to keep liquids in and out, so it can come along wherever your travels take you.

By Justin Fenner 11/03/2026

If all you’re going to do is look at it, a leather Dopp kit from a fashion house is a fine choice. But if you take travelling seriously—and do it often, for business, pleasure, or both—such a bag will inevitably end up blemished with droplets of water or stained by errant flecks of toothpaste. Get stuck with a cavalier team of baggage handlers, and it can even get soaked in your favourite fragrance or anti-ageing serum.

But Patricks, the high-performance Australian grooming brand stocked in Harrods and Bergdorf Goodman, has a solution. Its limited-edition bathroom bag, called BB1, is purpose-built to protect everything inside and out. Conceived by industrial designer George Cunningham with brand founder Patrick Kidd, the cuboid design is executed in a water-resistant recycled nylon you can rinse clean. It’s lined with a thin layer of shock-absorbing foam to safeguard your products, but if a bottle somehow gets cracked in transit, the two-way water-resistant zippers and sealed seams (which keep liquids from seeping in or out) ensure that whatever leaks won’t ruin your cashmere. Inside, two dual-sided zippered compartments are ideally sized to fit toothbrushes, razors, and other small essentials.

And though its clean lines and rugged construction make it undeniably masculine, its greatest feature is borrowed from women’s makeup bags. Like the best of these, BB1 unzips to lie flat, giving you unobstructed access to everything inside. Well, you and the 999 other gentlemen who move fast enough to snag one. $289

1. Hanging Loop 

The G-hook system isn’t just a stylish handle: You can also use it to hang the bag from a hook or secure it to your carry-on.

2. Two-Way Zipper

The closures are water-resistant in both directions, meaning liquids won’t get in or out.

3. Fold-flat Construction

BB1 opens to 180 degrees, letting you scan its 4.2-litre capacity at a quick glance.

4. Technical-Fabric Shell

The durable recycled-nylon is easy to maintain and woven to survive splashes and leaks from your go-to products.

You Can Now Place Bets on the Future Prices of Rolex Models

And which models will get discontinued next, thanks to a new collaboration between Kalshi and Bezel.

By Nicole Hoey 11/03/2026

You can bet on pretty much anything these days, from when Taylor Swift and Travis Kelce will get married to who will be the next James Bond—and now that includes the Rollies on your wrist, or on your wishlist.

Prediction market platform Kalshi, regulated in the U.S., and luxe watch marketplace Bezel have teamed up on a new platform called Watch Futures that allows users to splash down cash on where they think the prices of a particular luxe timepiece are going, whether that’s a Rolex Submariner or a coveted Patek Philippe, Time & Tide reported.

You can also place a wager on which models might be discontinued, as well as any future launches from the top watchmakers on the new platform; with Watches and Wonders coming up, it’s certainly a well-timed launch that could see a lot of activity as a slew of new releases are announced at the event.

Watch Futures is all based on Beztimate, Bezel’s system (once used only internally) to help it accurately calculate the market price of a timepiece. It draws data from real-time transactions, live bids, verified sales, and other market offers to spawn its own series of independent valuation models to establish a watch’s value. From there, it’s up to bettors to place their wagers, and then the platform will showcase any price fluctuations or other updates as time goes on.

This new platform could have some pretty large implications for the watch industry.  As any horological savant would know, the internet and collectors alike are constantly chattering about which models are on the way out or when a certain timepiece of the moment’s time in the limelight will fade, of course, having a large impact on the prices of said model. And now, a Watch Futures user can have a direct stake in where a model is headed—and if they own said timepiece, it can be a protection from dwindling values on the marketplace, say, if a user places a bet on their model losing value and that actually comes to fruition.

To see Watch Futures in real time (and scope out how some pieces in your collection are faring), you can use the Kalshi app or its website.

Mauve on Up

Brisbane boutique stay Miss Midgley’s offers a viscerally human experience—especially if you dig pink.

By Horacio Silva 17/12/2025

On a sun-bleached corner of Brisbane’s New Farm, where the scent of frangipani mingles with the clink of coffee cups, stands a building that has lived more lives than most people. Once a premier’s residence, an orphanage, a hospital and a private school, the 160-year-old stone structure now finds itself reborn as Miss Midgley’s—a boutique stay that teaches a masterclass in how to make heritage feel modern.

Designed and run by architect-mother-daughter duo Lisa and Isabella White, Miss Midgley’s captures the cultural confidence of a city in bloom. Nowhere is that new confidence more visible than along James Street—the leafy, slow-burn heart of the city’s fashion and dining scene—where Miss Midgley’s sits quietly at the edge, its shell-pink façade glowing in the subtropical light.

Built of Brisbane’s rare volcanic tuff, the building’s soft mauves and pinks are more than aesthetic; they are its identity. Locals still remember its 1950s incarnation as the Pink Flats, and the Whites have honoured that legacy with a contemporary blush-toned exterior, chosen to harmonise with the stone’s peachy undertones. Inside, those hues continue in dusty terracottas, russets and the faint shimmer of brass tapware. “Design can’t afford to be for the sake of fashion,” Isabella White has said. “It has to respond to what’s in front of you.”

That sentiment is tangible in every corner. Five apartments, each with their own idiosyncratic floor plan, occupy the building. Ceilings bloom with heritage plasterwork, 19th-century wallpaper fragments have been preserved in the kitchens, and tiny hand-painted notes left by the architects point out original quirks: a misaligned beam here, a hidden archway there. It’s a kind of adult treasure hunt for design lovers, where discovery feels personal and unforced.

Even the picket fence, a heritage requirement, has been reimagined in corten steel—a sly nod to regulation turned into sculpture. It’s this blend of reverence and rebellion that gives Miss Midgley’s its edge: heritage without starch, nostalgia without sentimentality.

True to Brisbane’s easy elegance, luxury here is measured not in marble or minibar but in proportion, privacy, and personality. Each apartment—from the Drawing Room and the Assembly Hall to the Principal’s Office—is a self-contained sanctuary with its own kitchen, large bathroom and outdoor space. The ground-floor units open onto leafy courtyards and welcome small dogs; upstairs, the larger suites spill onto verandahs shaded by jacarandas.

At the heart of the property lies a solar-heated pool hemmed with tropical greenery and fringed umbrellas—more mid-century Palm Springs than colonial Brisbane. Around it, guests share a petite laundry, a communal library and that rarest of urban luxuries: a car park per apartment. The atmosphere is quietly collegiate—a handful of travellers who might nod to each other on the stairs but otherwise inhabit their own creative bubbles.

The hotel’s namesake, Annie Midgley, lends the project both its name and its spirit. An ambidextrous artist and teacher, she famously instructed two students at once, writing with both hands simultaneously—a fitting metaphor for the dual vision the Whites bring to the building: one hand rooted in history, the other sketching toward the future. “Not famous, yet known,” goes the property’s understated tagline—and indeed, Miss Midgley’s has quietly become that most desirable of addresses: the one whispered about by people who know.

Sustainability isn’t an accessory here; it’s structural. The adaptive reuse of the heritage building is its boldest environmental act. Solar panels power the property; an electric heat pump warms the pool; recycled decking and tiles frame the courtyard. The metre-thick tuff walls regulate temperature naturally, and the amenities follow suit—refillable bath products, biodegradable pods, Seljak blankets spun from textile off-cuts, and compendiums wrapped in Australian-made kangaroo leather. It’s slow luxury in the truest sense.

In a world of carbon-copy hotels, Miss Midgley’s feels deeply human—a place where history isn’t curated behind glass but lives in the warmth of stone and the flicker of afternoon light. The lesson it offers is simple and resonant: that the most elegant modernity often comes not from reinvention, but from listening to what’s already there.
