I get the feeling there are many people here who would very much enjoy this one: https://youtu.be/1nLHIM2IPRY

Spoiler alert: the Saturn 5 rocket engines used the exhaust air from a 50000-odd HP jet turbine engine, to help cool the main rocket nozzle extension... and there are 5 of them.

😶

That is old tech from the stoneage - before rocket engines where 3D-printed and used for more than just one liftoff.

@Oktokolo for me it's more about the engineering process, problems encountered and solved, etc.. modern and previous generation tech all encounter different issues, so I definitely don't discard it because "it's old", I admire it more instead.

FWIW, I own and use a 1952 Rockwell Beaver table saw... Even got a new saw blade for it just last week. Should I discard it because it's twice my age..? (Spoiler: not gonna happen)

@ZaLiTHkA Nah, that saw is probably still good. But i wouldn't use Saturn 5 rocket engines for my next trip to the moon.
