Andy Green is the current holder of the World Land speed record, and the first person to break the sound barrier on land. On 25 September 1997 in ThrustSSC he beat the previous record in Black Rock Desert, USA, reaching a speed of 714.144 mph (1149.30 km/h). On October 15, 1997, exactly 50 years and 1 day after the sound barrier was broken in aerial flight by Chuck Yeager, Andy Green reached 763.035 mph (1227.99 km/h), the first supersonic record (Mach 1.016). His call sign was "Dead Dog".
Andy is now working with Richard Noble again on their new record attempt to break the 1,000 mph mark with Bloodhound SSC
