Space Shuttle Main Engines Upgrades
One of the main references on my RS-25 reflight video is this NTRS presentation on the multiple generations of the Space Shuttle Main Engine design. The engines were upgraded over time and swapped between orbiters as missions required working engines.
And of course now these veteran engines are going for one last spaceflight together.
I'm trying to figure out if there's a good way to visualize the engines being swapped between orbiters during the program.

Was the STS ever going to be what it was presented to be?
Scott, Richard Feynman (someone I trust on process analysis as well as physics), was very critical of the Block One engine engineering and safety/risk analysis. Do you have or know of a good detailed description of the technical differences between the Blocks?
