.. and today in the US, where it is still the 15th October, it is the 15th anniversary
of when Wing Commander Andy Green, a British Royal Air Force pilot, became the
first person to break the sound barrier on land in 1997.
The record took place 50 years and 1 day after Yeager's first supersonic flight.
Green used a jet propelled vehicle called ThrustSSC and reached a speed of 1149 km/h.
