Felix Baumgartner set multiple world records in 2012 during a fall that broke the sound barrier.

Boom Supersonic is the first independently-funded jet to break the sound barrier.

Extreme athlete Felix Baumgartner, the first skydiver to fall faster than the speed of sound more than a decade ago, died in a crash Thursday along the eastern coast of Italy.

In 2023, Wetherspoons abandoned plans to erect a 43ft high sound barrier, dubbed “taller than the Berlin Wall” by one objector, after strong local opposition.
