London to New York in 3.5 hours: How Boom Supersonic is learning from Concorde’s mistakes
More than two decades after Europe’s failed attempt at a supersonic airliner, the USA is on track to make it work.
Could all our future planes travel faster than the speed of sound? It’s been more than 20 years since the last supersonic passenger flight took off, but a US company wants to bring it back.
Boom Supersonic, based in Colorado, is developing the world’s first supersonic passenger aircraft since the demise of Concorde. While the full-size aircraft is still a few years away, the company has reached a milestone in the project when it successfully broke the sound barrier with its small-scale test aircraft on Tuesday.
The XB-1, affectionately known as the ‘Baby Boom’, is a one-third-scale demonstrator used to test the technology that Boom will employ in its full-scale aircraft. Yesterday, the XB-1 achieved Mach 1.05 within about 11 minutes of taking off.
“XB-1’s supersonic flight demonstrates that the technology for passenger supersonic flight has arrived,” Boom founder and CEO Blake Scholl said in a statement. “A small band of talented and dedicated engineers has accomplished what previously took governments and billions of dollars”.
The aircraft, which flew for the first time in March, is made almost completely from lightweight carbon fibre. It uses an augmented reality vision system to help with landing, since its long nose and high-angle approach can make it difficult for pilots to see.
“The future of aviation is here and now,” told Amy Marino Spowart, president and CEO of the National Aeronautic Association. “Not only is there hope for faster and better commercial flight, but Boom proves that it can be done sustainably”.
Boom’s Overture airliner will be the first supersonic passenger aircraft in more than two decades. But can it succeed where past efforts to get us travelling faster have failed?
A short history of supersonic passenger planes
Back in the 1950s, everyone was convinced that supersonic was the next big thing in air travel. Having just about mastered the jet engine, the aviation industry was inspired by Chuck Yeager, who was the first to break the sound barrier in 1947. Major manufacturers set about designing a commerical passenger aircraft that could do the same thing.
Boeing, certain that the mighty 747 would be the last subsonic aircraft it produced, began working on the 2707 SST (supersonic transport). Lockheed proposed the L-2000, a supersonic aircraft that could carry 250 passengers. However, neither aircraft went into production.
Just two supersonic passenger planes have ever entered service – the Russian Tupolev Tu-144 and the venerable Anglo-French Concorde. In total, 20 Concordes were built, although only 14 flew in passenger service. Russia built 16 Tu-144s.
The Tu-144 – affectionately known in the industry as the ‘Concordski’ – entered service in 1975 but was retired from passenger service just three years later. Concorde lasted longer, flying from 1976 until 2003.
So, why did aviation give up on supersonic passenger transport so soon?
What was the problem with Concorde?
The appetite for a supersonic passenger plane was strong. By the time Concorde took its first test flight, orders had been received for more than 100 aircraft from dozens of major airlines of the day. Pan Am, American Airlines, BOAC, and Lufthansa were counted among the many carriers keen to fly faster routes.
But even before the aircraft entered service with British Airways and Air France, many of these orders had been cancelled. Three main problems existed with the plane – noise, smoke, and money.
The 1973 stock market crash and an oil crisis in the same year made airlines rather cautious about aircraft that consumed a lot of fuel. Reports suggested that Concorde achieved a per-passenger fuel efficiency of 15.8 mpg (17.8 L/100 km), making it a rather thirsty option.
In comparison, the Boeing 747 would achieve a per-passenger mpg rate of 46.4 (6.1 L/100 km), and the popular Douglas DC-10 managed as high as 53.6 mpg (5.3 L/100 km).
Coupled with the worries about fuel consumption, the noise of Concorde’s sonic boom caused issues that made its planned routes with potential buyers unviable. Complaints of broken windows and cracked plaster from households under the flight path, and even farmers reporting panic amongst livestock, meant Concorde was banned from going supersonic over land.
As a result, the plane was forced to fly subsonic until it got over the open ocean. This meant Concorde’s high-speed routes were mainly focused between Europe and the USA, making the plane less attractive to potential buyers who wanted to operate routes over land.
In the end, only Air France and British Airways ever flew the Concorde. Putting the aircraft into passenger operation presented yet another challenge, however, as the costs to power such a fuel-hungry jet with a modest passenger load of around 100 people made the business case very weak.
In order to make Concorde profitable, both airlines had to charge eye-watering prices for tickets. According to the National Air and Space Museum, British Airways would charge around $12,000 (€11,550) for a round trip between London and New York. Adjusted for inflation, that shakes out to around $66,000 (€63,500) in today’s money.
The companies made a go out of it – just about. Despite the high costs, both airlines managed to sell tickets, with passengers seeing their trip as a ‘once in a lifetime’ opportunity. But the cabin was noisy, smelly, and cramped – hardly a luxury experience for the money.
The death blow came when an Air France Concorde was involved in a fatal crash in 2000. Debris on the runway was blamed for rupturing a tyre, which then punctured one of the fuel tanks. This caused the plane to crash into a nearby hotel, claiming the lives of 113 people.
While both BA and Air France cited high maintenance costs for the retirement of their Concorde fleets in 2003, there were many factors at play. In truth, the market had moved on, and a trend for low-cost flying and more efficient aircraft had made Concorde redundant.
Will Boom Supersonic succeed where Concorde failed?
If you believe the hype, Boom claims to have already dealt with many of the issues that contributed to Concorde’s demise. Noise, cost, and efficiency are high priorities for the company to tackle.
Part of Concorde’s noise profile was a direct result of the engines using afterburners to achieve supersonic flight. Overture will not use afterburners, which should significantly reduce fuel consumption and the associated noise.
For passengers, the cabin is a world away from the cramped, noisy environment on Concorde. Advanced soundproofing measures mean it shouldn’t seem any louder than a conventional jet aircraft, and the company has already floated some designs for its interiors that look suitably luxurious and comfortable.
The company has developed its own engine solution that it says will reduce fuel consumption. These engines are designed to run on 100 per cent sustainable aviation fuel which, although not available at scale yet, would further reduce its environmental impact.
Overture hasn’t quite managed to eliminate the sonic boom effect, but thanks to more optimised aerodynamics, the impact will be reduced significantly. The company promises that Overture will be able to fly over land at Mach 0.94, about 20 per cent faster than subsonic aircraft, without breaking the sound barrier.
For now, the supersonic aircraft would be restricted to breaking the sound barrier over water. Boom says there are more than 600 transoceanic routes on which Overture could provide a supersonic solution without changing current regulations relating to sonic booms.
“Overture was created to achieve optimal performance while meeting our stringent safety and sustainability requirements,” says Boom Supersonic. “We are leveraging more than fifty years of advancements in aerodynamics, materials, and propulsion to build economically and environmentally viable supersonic aeroplanes”.
But what of the market demand? By the end of Concorde’s lifespan, British Airways said it was selling only around half of its available tickets. Air France, still suffering from the tragic crash in 2000, was selling less, only around 35 per cent.
Concorde’s ticket prices were up there in the ultra-luxury category. In contrast, Boom is targeting business travellers, and pricing seats accordingly. Early estimates suggest a round trip Europe to USA ticket for around $5,000 (€4,800), in the ballpark of what passengers pay for business class seats on regular jets today.
“Today, there’s both the market demand and the technology to enable mainstream supersonic travel,” the company says. “Business and leisure travel has continued to grow, and travellers are willing to pay for speed.”
Boom is targeting 2029 for the entry into service of its Overture airliner. It has already had orders for 130 aircraft from multiple global airlines, including American Airlines, United, and Japan Airlines. If it can steer clear of the pitfalls that ended Concorde’s career, supersonic travel may well be back on the cards.

When is the Sistine Chapel closed? What to know about visiting Rome following Pope Francis’ death
Tourists who have booked to visit Rome in the coming weeks will experience the city during a rare historical moment.
Following the death of Pope Francis on 21 April, a series of religious rituals and procedures will be enacted that might impact travel plans.
The Argentinian-born pontiff died on Monday of a stroke, which triggered a coma and “irreversible” heart failure, the Vatican announced.
The Sistine Chapel will be closed to the public while it is used for voting on the new pope – a process that will see the famous room closed for over a week.
Crowds and queues around the Vatican are expected to be particularly heavy, especially given the celebrations for the Catholic Church’s 2025 Jubilee Year are already drawing an increased number of visitors.
Here’s what to know about expected travel disruptions in Rome, or, if you’re planning a trip to witness some of the religious traditions, where you can participate in them.
When will the Sistine Chapel be closed?
Travellers to Rome in the next few weeks have been warned to expect closures, visitor restrictions and crowds at some of the city’s main attractions.
Rome’s key tourist sites within the Vatican – the heart of the Catholic Church – will now be absorbed by mourning and reelection procedures.
Around 15-20 days after the pontiff’s death, the conclave will begin, a storied process to determine the next pope.
This strictly confidential gathering sees Roman Catholic cardinals locked inside the Sistine Chapel until a decision is made.
As such, the room adorned by Michelangelo’s frescoed tour de force will be closed for about a week before the conclave begins and will remain closed for the entire duration of the process.
It will likely open again a couple of days after the conclave ends, as it has done after the death of previous Popes.
The Vatican City State has announced that the Sistine Chapel will be closed to the public from Monday 28 April, for the requirements of the conclave.
The chapel is accessed through the Vatican Museums. These will remain open to visitors with all other parts accessible, including the Raphael Rooms, according to tour operator Through Eternity Tours.
The Vatican Museums and the Castel Gandolfo Museum Complex will, however, be closed on 26 April as a sign of mourning for the funeral of Pope Francis.
Tours of the Necropolis of the Via Triumphalis and the Vatican Gardens will be suspended for security reasons, however, as the cardinals are bused back and forth from the chapel to their accommodation through the grounds.
The Vatican Museums states that all tickets, including for the Sistine Chapel, are non-refundable and dates, times or names cannot be modified.
If you have purchased tickets through a third-party operator, you should check their website or contact them about refunds or date changes.
Long queues and dress codes for St Peter’s Basilica
Tourists should expect limited access to St Peter’s Basilica, where Pope Francis’ body is now lying in state from today, 23 April.
As mourners flock to pay their respects, tourists wanting to visit the church should expect lengthy queues and heightened security.
The dress code for visiting the sacred site will be strictly enforced. This includes having shoulders and knees covered and avoiding wearing short skirts, shorts, flip-flops and sleeveless tops.
Some areas of the basilica may not be accessible, including the dome. Guided tours to the basilica are suspended as access is via the Sistine Chapel.
Pope Francis requested to be buried in the Basilica of Santa Maria Maggiore, a majestic UNESCO-designated sanctuary containing a piece of the Holy Crib and a venerated icon of the Virgin Mary as the protector of the Roman people.
Access to the church is likely to be restricted due to funeral preparations and the burial.
Millions expected in Rome for Pope’s funeral
While it may be disappointing to forgo seeing the Sistine Chapel or St Peter’s Basilica, a visit in this period can also be a once-in-a-lifetime experience (the Italian expression for ‘once in a blue moon’ is ‘every time a pope dies’).
Visitors from around the world are expected to descend on Rome in the coming weeks for a chance to witness this monumental event for the Catholic Church.
“Historically, during the passing of a pope – as we experienced firsthand in April 2005 during the death of Pope John Paul II – travellers witnessed a profound moment of history,” James Ridgway, CEO of Christian travel specialist ETS, told Travel Weekly.
“While some sites around St. Peter’s Basilica and Vatican City experienced closures or restricted access, many travellers were able to participate in public gatherings, memorials and prayer services, creating a deeply meaningful experience.”
If you are planning a short-notice trip to participate in some of the funeral and reelection events, you should expect higher flight prices.
“We’ll definitely see an increase in flight prices to Rome and to Italy over the next few weeks, as the faithful flock to pay their respects and potentially to see the announcement of the new Pope,” Angus Kidman, travel expert at Finder, told Australian site news.com.au.
Hotel prices in Rome are also likely to rise as demand increases, says Tim Hentschel, the co-founder and CEO of travel company HotelPlanner, while some shops and restaurants may be closed as a sign of respect.
The Pope’s body will be lying in state for public viewing in St Peter’s from 23 April until Saturday, 26 April, when the funeral will take place in St Peter’s Square.
The chapel where he is on display is accessible on 23 April from 11 am to midnight, 24 April from 7 am to midnight, and 25 April from 7 am to 7 pm.
The funeral is expected to draw huge crowds, possibly larger than that of Pope John Paul II in 2005, which was attended by approximately four million people.
Where to witness the announcement of the new pope
When the conclave begins, St. Peter’s Square will remain open, but it will be packed with visitors and media.
The outcome of voting rounds is indicated via smoke released from the chapel chimney – black for inconclusive, white for the successful election of a new pope.
According to the National Catholic Reporter, you can see the smoke from the chapel twice daily – around noon after the first two ballots and again at 7 pm after the last round of voting.
White smoke might appear earlier, at around 10.30 am or 5.30 pm.

Cracow, Queensland: A hidden gem in the Australian Outback with a storied past
Not all roads lead to Cracow. In fact, getting to this town in the heart of the Outback requires careful preparation.
Halfway there, the GPS signal disappears. And, as there are no petrol stations along the route, you need to bring an adequate supply of fuel if you don’t want to get stuck in the middle of nowhere.
Cracow, however, rewards the traveller’s effort. After a long, pothole-laden journey, you finally see a town that — although it does not resemble Kraków, the better-known Polish city — has its own subtly charming, albeit austere, character.
The town’s ties to Poland remain unclear.
Some say that the founder of the first settlement in the area had a Polish wife and was moved by her compatriots’ struggle for freedom in the 19th century.
But others believe that the name comes from the rustling of dry branches (or crack), which are abundant in this harsh climate.
Either way, what is beyond doubt is that this place has long attracted people with an explorer’s spirit and a desire for something more than an ordinary life.
Cracow was one of the last towns to emerge during the gold rush of the 1930s. At its peak, it had a bustling population of around 10,000 people, and almost 20,000 kg of gold was mined locally.
Eventually, its good fortune came to an end — the gold mine closed and Cracow turned into a ghost town.
The population dropped to around 50, and its centre was filled with rusty buildings no longer reminiscent of its past vibrancy.
Prominent among these dilapidated locales, however, is the Cracow Hotel and Pub, run by Stuart and Nikki Burke along with their two children, Brophy and Chilli.
Although the local gold mine has resumed operations after being deserted for years, the town is far from revived.
Euronews headed to Cracow to find out how a pub in the middle of nowhere works, and to tell the story of the people who have decided to breathe life into this forgotten place.
A magnet for adventurers
Cracow Pub and Hotel owner Stuart Burke is one of those rare free spirits willing to choose the Australian wilderness as his home.
Stuart was part of a troupe of tent boxers in his youth and participated in fights under the nickname “Kid Goanna”. He and other fighters travelled from town to town, offering a rare moment of entertainment for hard-working farmers and miners in the Australian Outback.
The Cracow Hotel had been in the hands of another boxer before — for many years it was owned by legendary boxer Fred Brophy, an icon of the Australian tent boxing scene.
It was with this troupe that Stuart Burke first came to town, and the Cracow pub is where he met his future wife, Nikki.
When Brophy announced that he was going to sell the property, the Burkes immediately decided to buy it — to ensure that the Cracow story continued.
“Twenty-three years later, we’re married, have two children and run the pub where we met,” says Stuart.
But life in the Australian wilderness is far from perfect. Parcels cannot be sent to Cracow, and the nearest shop is a 3.5-hour drive away. The Burkes do what they can, but at the height of the tourist season they have to travel this route up to once a week.
Stuart isn’t complaining, however: “We didn’t even have a road until 10 years ago.”
Despite the obvious challenges of living in Cracow, the family cannot imagine living anywhere else. They agree that Cracow is their home, and running the pub is their way of life. As Nikki recalls, since its founding in 1938, the pub has showed its “ability to survive” even through the worst of times.
‘You have to get lost’ in order to get to Cracow
Stuart stresses that there are two ways to get to Cracow. “You either have to be very meticulous to get to us or get very, very lost!”
The spiritual atmosphere and reputation of the last town of the gold rush era attracts a particular type of visitor.
“All types of people visit us, but especially vagabonds, travellers and even rock stars,” he says. The walls and ceilings of the pub, covered from top to bottom with visitors’ signatures, are an archive of all those who have managed to reach this remote place.
But Cracow values loyalty above all: the area’s permanent residents visit the pub regularly, and the staff know their orders by heart. It is a place to exchange good and bad news, overhear local gossip and complain about the weather.
The pub’s owners are particularly proud that they manage to attract customers despite not having the poker machines, so-called ‘pokies’, that are booming in popularity in the Australian Outback.
Gambling addiction is one of the country’s leading public health challenges. Australians lose more than $25bn (€13.9bn) each year on legal gambling, making them the world “leaders” in terms of per capita losses.
The Cracow Pub is resisting these trends by trying to build a local identity around other activities.
The owners recently became involved in organising a rally of Cracovians — both descendants of former miners and those whose ties to the town are purely emotional.
Residents also recognise the role played by the reopened mine. Although it has not contributed to significant population growth, it is sustaining the local community.
The Cracowians stubbornly refuse to let their town disappear from the map.
Is it haunted?
In recent years, the town has gained yet another face and one straight out of a horror film.
A film crew has moved into the abandoned hospital in Cracow, and the town has grown into a mecca for independent horror films.
Special effects creator and make-up artist Kadey Platt, who works as a bartender in the Cracow pub after hours, explains that although she ended up in the town by accident, she has now lived there for two years.
“I’m a city girl. I never imagined myself in a place like this,” she says.
Platt and her team were looking for a location for a horror film about a zombie kangaroo. The strangeness of the Cracow pub seemed ideal, and she later decided to stay on.
Along with her crew, she bought a nearby abandoned hospital and turned it into their command centre. As she recalls, “the quietness that Cracow offers is conducive to creativity. There are no distractions, instead you can find a kangaroo mum relaxing by the threshold”.
Platt emphasises that the contrast between the quiet town and the lively pub never ceases to amaze her. “These walls are full of history,” she says.
Small-town ghosts
The spirits of Cracow are particularly looked after by Brophy, the 20-year-old son of the pub’s owners, who was named after the legendary boxer through whom his parents met.
Together with his mum, Brophy has been researching unmarked graves in Cracow. Thanks to their efforts, they were able to restore the cemetery and commemorate the miners and locals buried there whose names are no longer remembered.
As he points out, although no one has found gold in Cracow on their own for years, the ground here hides other stories.
Brophy is interested in the fate of the indigenous inhabitants of the area — their culture, customs and tragic fates. He explores the traces of massacres perpetrated on Aboriginal people by white settlers in pursuit of gold. “It’s an unwritten chapter,” he says.
Just as we were about to leave Cracow, a car pulled up in front of the pub.
One of the locals came up to Brophy with a box full of old newspaper cuttings, found somewhere in an attic in Cracow. “I’ve got some new stories for you,” he said.
And so we saw with our own eyes how a pub in the Australian wilderness had become a custodian of the memory of a small town and its intricate history.
“That’s the way it is with Cracow,” says Stuart. “It may not be on the way, but you can’t stop coming back to it!”
