It's important to remember that while the SR-71 was introduced in the late 60s, its engine was developed in the 50s, based off a pre-existing design from the 40s. They were actually initially developed for a boat plane.

Pretty wild huh? Once upon a time the gear shifts in automatic transmissions were handled by a hydraulic "computer".

Very wild indeed! Thank you for sharing that. Though, I don't even know what I'm looking at ! (*and don't say 'automatic transmission gearbox' :-p ~ I mean to say this is all foreign to me and while I can appreciate it, I certainly don't understand it)

Hydraulic fluid goes brrr, car goes vroom! That's about the extent of my understanding.
When I think "analog computer", I think of something that's still an electrical circuit, but using op-amps instead of transistors. Hydraulics, wow - did not see that coming from the title.
