I was recently rewatching it, and maybe I fell asleep or something, but there's no explanation on how they fly? I don't see any engines or propellers like the Goliath in Laputa. Does anyone have ideas or an explanation?

I haven't read any manga, maybe it's explained there?

Edit: solved, thank you all very much!

New to the game, did I do okay?
