Funny, I put parachutes on my airplanes in kerbal space program (as a safety feature) but never considered what the real-life analogue to that would be. Turns out it's very similar!

Just so its clear, Kerbal is the analog.

Analogue means having the same function. It does not say which came first.

False. Analogue does not mean having the same function.

Analogue, in this sense, means some action or thing seen as comparable to another.

If something is analogous of, or to something, it is proportional to something else.

The proportionality describes a primary/secondary relationship. If two actions/things are entirely comparable - i.e. orthagonality approximating 0.0 - then they are not analogues, but rather equivalents.

Something may be a poor comparison to another thing, but still be an analogue - albeit, a poor analogue in comparison to some other, original, instance.

Yes that's where the word comes from. I was describing how the word was used here. You quibble with established usage. https://www.merriam-webster.com/dictionary/analogue#h1
