Slop? How dare you. This was a hand-crafted artisanal meme that took me a whole night in GIMP to make!

Cowbee's Law: Effective agitprop will make you enemies.
The RS-25 is the space shuttle main engine, and a major reason the space shuttle never achieved its planned flight cadence was that the engines required a significant amount of rebuilding between each flight. The way they were used on the shuttle was to light them with the launch platform holding the shuttle down and make sure they were firing well before lighting off the SRBs (which cannot be shut down once lit) and releasing the launch clamps.
The Falcon (and to some limited degree Starship) are most of what I was referring to with "a few recent reusable first stages"
