Boom Supersonic is developing Overture, a supersonic aircraft designed to carry up to 80 passengers at Mach 1.7, aimed at restoring supersonic flight. Environmental concerns raised by Anna Hughes from Flight Free UK highlight the significant energy use and carbon emissions associated with supersonic travel.

While Overture is intended to run on 100% sustainable aviation fuel, Hughes argues that SAF currently represents less than 1% of aviation fuel use and its benefits are uncertain. Additionally, noise pollution and the sonic boom associated with supersonic flight remain major challenges. Despite these concerns, Boom's CEO Blake Scholl advocates for technological advancements to make supersonic travel viable again.
