Boom Supersonic made history this week as its XB-1 aircraft achieved the remarkable milestone of breaking the sound barrier, becoming the first independently funded jet to do so. Accelerated to Mach 1.05 during its test flight over the Mojave Desert at approximately 35,000 feet, this achievement has revived discussions around the potential for commercial supersonic travel, which has been largely dormant since the last flight of the Concorde more than two decades ago.
The test flight took place on January 27, 2025, above delighted observers who witnessed the aircraft soar through the air. The significance of this event cannot be overstated; it aligns with the legacy of aviation hero Charles “Chuck” Yeager, who famously broke the sound barrier himself back in 1947. Boom Supersonic's mission is clear: to revive supersonic travel, reintroducing it to commercial aviation, which has faced numerous technological and environmental challenges.
“XB-1’s supersonic flight demonstrates the technology for passenger supersonic flight has arrived,” stated Blake Scholl, the founder and CEO of Boom Supersonic. This successful flight serves as proof of concept for the company’s innovative approach to commercial air travel. The XB-1 itself is constructed primarily from lightweight carbon fiber and incorporates advanced technology such as augmented reality systems to assist pilots during landing — especially important due to its long nose design.
Future plans for Boom include the development of the Overture commercial airliner, which is expected to carry up to 80 passengers at speeds nearly double those of traditional subsonic jets. This could mark the beginning of faster international travel, provided it can navigate the challenges faced by the beleaguered Concorde. Notably, Boom has already secured commitments from major airlines, including American Airlines and United Airlines, and has amassed orders and pre-orders for 130 aircraft.
Yet, the reintroduction of supersonic travel will not be without its hurdles. Commercial flights may face restrictions similar to those the Concorde encountered, especially concerning noise regulations. Sonic booms, the loud noise produced when aircraft exceed the speed of sound, can cause significant disruptions on the ground. These limitations may mean future supersonic flights will primarily operate over oceans, as the aircraft would need to slow down significantly when flying over land.
Technology is also advancing to create quieter supersonic aircraft. NASA is actively researching ways to design planes with softer sonic booms, and Boeing has also embarked on developing supersonic flight prototypes. The promise of new technology suggests future supersonic travel could be both faster and more environmentally friendly than the past incarnations, allaying some of the air traffic concerns associated with the Concorde.
Historically, the Concorde was the only supersonic commercial airliner to achieve operational status and holds the record for the fastest transatlantic flight — the breathtaking duration of 2 hours, 52 minutes from London to New York. Yet, the Concorde was grounded for various reasons, including ecological concerns and prohibitive operating costs, ceasing operations entirely by 2003. Only 20 units were ever constructed, with tragically few seeing prolonged service due to the high expenses associated with flying them.
Even the tragic crash of Air France Flight 4590 on July 25, 2000, which claimed the lives of all on board and four on the ground, significantly marred the aircraft's reputation. The disaster highlighted the vulnerabilities associated with high-speed passenger travel and led to intense scrutiny of supersonic travel's safety protocols.
Today, Boom Supersonic's advancements provide hope for the future of aviation, as it strives to combine speed with sustainability. “The future of aviation is here and now,” commented Amy Marino Spowart, President and CEO of the National Aeronautic Association. The ambition to revive commercial supersonic travel faces the undeniable scrutiny of environmental standards and public consciousness about climate change, all of which must be balanced alongside the excitement of returning to faster-than-sound travel.
The XB-1 flight marks only the start of what Boom plans for the future. With technology becoming increasingly sophisticated, the possibility of affordable, faster travel across the globe moves closer to realization. There is a palpable sense of anticipation as the world waits to see if the promise of supersonic travel will come to fruition once more.
