Boom Supersonic’s historic supersonic flight on January 28 did not generate a sonic boom, as planned. According to Blake Scholl, company founder, this was intentional and achieved through “well-known physics called Mach cutoff.” At high altitudes, the sound of breaking the speed barrier “refracts” upwards, making it impossible for people on the ground to hear. The flight’s profile was calculated using advanced technology to minimize disruptions.
While the lack of a sonic boom is a notable achievement, Scholl acknowledges that more work is needed to address variables such as atmospheric conditions and aircraft speeds. Additionally, regulatory hurdles remain, including a federal ban on overland supersonic flight. Despite this, Scholl remains optimistic, citing the success of the recent flight as a step towards convincing authorities to lift the ban.
Boom’s Overture supersonic airliner is currently under development, with an expected assembly timeline of three years and entry into service by 2029. With advancements in technology, Scholl aims to make supersonic flight more accessible and efficient, paving the way for a new era in air travel.
