The Concorde may have retired over two decades ago, but the potential return of supersonic travel is making waves in the aviation world. Imagine flying from London to New York City in just three hours! That’s the allure of the Concorde, which flew at a maximum speed of 1,345 miles per hour (2,179 kilometers per hour). However, a long-standing U.S. ban on supersonic flights over land restricted its routes—and still affects modern commercial aircraft. But things might be changing.
Recently, President Donald Trump signed an executive order reversing the 1973 ban on civilian supersonic flights. This directive instructs the Federal Aviation Administration (FAA) to create noise certification standards for these aircraft, potentially paving the way for faster journeys—if manufacturers can innovate quieter and more cost-effective designs.
The Sound Barrier: Challenges and Innovations
When planes exceed the speed of sound, known as Mach 1 (around 767 miles per hour or 1,234 kilometers per hour), they generate a loud explosive noise due to shock waves—think of it like thunder startling residents underneath. This prompted the FAA to ban non-military supersonic aircraft from flying over land back in 1973 because technology at the time couldn’t adequately address the noise. Thankfully, research since then has illuminated ways to diminish the sound of supersonic travel.
Boom Supersonic’s X-B1 Plane Breaks Sound Barrier, Bringing Supersonic Travel Closer to Reality
Meet Boom Overture: A New Era of Supersonic Travel
Enter Boom, a budding company based in Colorado actively developing the Boom Overture. Its current prototype, the XB-1, aims to fly at speeds of Mach 1.7, accommodating 64 to 80 passengers. As a frontrunner in this revitalized industry, Boom welcomed the recent regulatory change. Earlier this year, they successfully flew their experimental aircraft past the sound barrier for the first time, drawing interest from major airlines, including American Airlines and United Airlines.
New Rules for Supersonic Aircraft
Trump’s executive order isn’t without its stipulations. It mandates that the FAA repeal the supersonic speed limit only if these aircraft can avoid producing an audible sonic boom on the ground. The FAA is tasked with establishing a noise certification standard that balances community acceptability, economic viability, and technical feasibility. The White House claims advancements in aerospace engineering have made the prospect of supersonic flights not only possible but also safe and sustainable.
NASA’s Initiative to Mitigate Sonic Booms
In parallel, NASA is exploring ways to minimize the disruptive impact of sonic booms. Earlier this year, they began testing the engine of their X-59 research aircraft, developed to fly faster than sound with significantly reduced noise levels. According to NASA, communities beneath the flight path might only hear sonic “thumps” instead of booms. This aircraft is designed to lower the pressure change it creates as it passes overhead, leading to a quieter experience below.
Environmental Concerns: Addressing the Fallout
Despite the excitement surrounding supersonic travel, there are environmental implications to consider. Supersonic jets traditionally consume more fuel—Concorde, for instance, burned 22 tons of fuel per hour, which is double that of a Boeing 747 while carrying far fewer passengers, as reported by Transport & Environment. Boom is committed to employing sustainable alternative fuels to lessen the environmental footprint, but there are caveats. Given that these planes must soar at higher altitudes, their emissions could linger twenty times longer, which presents a significant challenge for sustainability.
The Cost of Speed: Are Supersonic Flights Viable?
Another hurdle lies in the financial model. With high operation expenses and premium pricing, supersonic flights are not inherently profitable. The Concorde struggled because fuel costs outweighed ticket revenue. Airlines aiming to capitalize on this market must devise a sustainable pricing strategy to attract customers willing to pay for quicker travel.
While lifting the ban is a step forward, there remains much work ahead before supersonic jets can routinely grace our skies.
What is the future of supersonic flights? Will they really be more affordable? These are pressing questions many are asking. The revival of supersonic travel holds remarkable promise, but it hinges on innovation, feasibility, and community acceptance.

Can supersonic flights return safely and sustainably? The recent regulatory changes suggest it’s possible, but new technologies will play a crucial role. As companies like Boom develop their supersonic airliners, we can expect a pivotal shift in air travel.
What challenges do supersonic flights face in terms of environmental impact? The increased fuel consumption and lingering emissions are substantial concerns. Sustainable aviation fuels could help, but they require extensive research and deployment.
Are there any companies currently working on supersonic aircraft? Yes, Boom Supersonic is a key player in this space, working on their Overture model, and they have garnered interest from established airlines.
What is the maximum speed of supersonic jets? Supersonic jets can exceed Mach 1, which is about 767 miles per hour (1,234 kilometers per hour). Some prototypes aim for even higher speeds, like Mach 1.7.
What historical significance does the Concorde hold? Concorde was a pioneering aircraft, showcasing the potential of supersonic travel and providing transatlantic flights that dramatically reduced travel time.
