I am a big fan of the 1997 Thrust SSC project and the current BloodHound SSC project. For the sheer engineering daring and boldness of ambition. For the mission to promote engineering and science as a profession and push back the frontiers of the possible. Here is the Cray Channels 1997 write up of the aerodynamic study done on a Cray C92 at the time.
And what does a Cray C92 look like ?
Available in Air or water cooling , 2 .. 4 CPUs with 32 .. 128 M Words of fast 64bit Bi-polar memory. Peek speed 4 Gflops. Also available with optional Solid State Storage device (up to 32 Gbytes) and massively parallel co-processor.
Both the Thrust SSC and Bloodhound SSC are on display at the Coventry Transport Museum in the UK.

Link to Facebook page of Bloodhound SSC project here . Yes I know Facebook was only founded 5 years after Thrust SSC grabbed the land speed record in 1997 and still holds it to this day in 2021 with no likely contenders now that the follow on Bloodhound project has stalled.
