QuoteNow I'm trying to imagine zero g vehicles, like some kind of gigantic-oar-propelled submarines, only oars spend half their motion outside the medium and that doesn't exactly work in the sky.

They could flap up and down. "Does ornithopting work in zero-g" is literally the discussion we are having right now. ^_^ Think davinci flying machine-looking things?

(Whether or not you could make an our with a large enough cross section to be efficient enough to be worth doing, and how light the vessel would have to be, these things I don't know--but imagining things like this flapping through the astral plane makes me happy?)

Hmm... this is what I'm imagining you could have, at least as far as a flappy oar was concerned.
