In a series of remarkable images, NASA has documented significant advancements in supersonic flight, including U.S. civilian jets breaking the sound barrier and Boom Supersonic’s innovative ‘boomless’ flight. These photos make the invisible phenomenon of sound waves visible, showcasing how Boom’s XB-1 research jet manages to achieve a quiet sonic boom, a potential game-changer for air travel. While interest in supersonic jets is on the rise, experts caution that commercial flights are still a way off as testing continues.
