The Land-Speed Record
Andy Green wasn’t finished yet. On the 15th of October 1997, Andy Green made another official attempt to set the land-speed record with the Thrust SSC. The speed was measured as an average of two runs made across a measured mile, both to be completed within an hour.
Green achieved an average speed across both races of 763.035 mph (1,226.986 km/h) and set the first supersonic record at Mach 1.016. Andy Green’s record-breaking ride was achieved a day after the 50th anniversary of the first supersonic flight by Chuck Yeager.
