Very cool! Thanks for sharing!

It is interesting that no faster-than-sound vehicle has achieved long-term commercially-successful application.

The Japanese Maglev train has hit 374 mph....but most high speed trains stay around 200 mph, which is still nothing to sneeze at....

The Concorde was the only supersonic transportation used in a commercial application. I guess my question is, does a vehicle have to remain in contact with the ground? Some definitions say they should remain on the ground but Wikipedia disagrees.

When I was a kid, I remember someone breaking the speed of sound on land. Give me a minute, I'll run a search.

1979, the Budweiser jet car broke the speed of sound on land at Edwards AFB. https://www.forbes.com/sites/jimclash/2016/08/08/interview-remember-the-budweiser-rocket-car-driver-stan-barrett-on-his-739-mph-run/#7f009dd2230d

Yes, that is the claim. However, they only did it once, in only one direction and briefly with the short duration assistance of an added sidewinder missile. The ThrustSSC used only the planned engines to make its two runs in the opposing directions in the allotted time to be the only vehicle to achieve the above the speed of sound record.
