Boom Supersonic successfully tested its XB-1 jet, breaking the sound barrier as part of its plan to bring back supersonic commercial flights, but experts warn of severe climate consequences. Supersonic jets burn significantly more fuel than standard aircraft, producing far more carbon emissions per passenger, and their high-altitude flights may further damage the ozone layer. While Boom claims sustainable aviation fuels (SAFs) could offset emissions, SAFs are scarce, expensive, and still produce carbon pollution, making their use in supersonic jets highly questionable. Additional challenges include the ban on supersonic travel over land due to noise concerns and unresolved issues with low-boom technology. As Boom moves toward commercial production of its Overture jet, critics argue that introducing a more energy-intensive form of aviation is irresponsible amid the worsening climate crisis.
