I enjoy fictional universes where spacecraft are in service for hundreds of years, because hey they're big and expensive and why build a new one when you can just maintain an old one.
@starkatt Ancient but loved and well maintained space craft are approximately 900% my aesthetic. Serenity is most of the reason I fell in love with Firefly. ♥ ♥ ♥ ♥

And Alex loves that ship with all his heart, and I can't help but love Alex for it. He's my favorite character. ♥️ ♥️ ♥️ ♥️
@acetone_kitten Revelation Space has possibly my favorite spaceship ever.
I've flown an airplane (Cessna 150) that was almost 50 years old. Aircraft have rigorous enough maintenance schedules that they can last basically forever. If you want you can slap in some more modern electronics but even that's not really required.
