That is until Thrust 2 took the record at Black Rock Desert due to insufficient good quality salt at Bonneville, plus the salt surface really didn't suit the car. Thrust SSC then raised the record to Mach 1.02 at Black Rock Desert. But unfortunately Black Rock is now unsuitable, both due to a couple of decades of Burning Man trashing the surface every year and the prolonged drought meaning the desert didn't flood and re-surface itself every winter like playas are supposed to.
"Glad you folks over there are aware." No, not most folks, just me. World land speed records are another one of my specialist areas of nerdery, together with space flight in general and the Apollo program in particular. I really wish Bloodhound had managed to set a new world land speed record at Hakskeenpan in South Africa, but the project was running out of steam anyway before covid and has made no progress after it.
