Aircraft are workable, although they need light weight, long wings,
and high flight speeds.  Propulsion is also a bit of a headache since
the atmosphere is not very useful as an oxidizer.

Balloons likewise are possible, and have been proposed.  Dirigibles --
rigid airships, aka zeppelins -- haven't been, that I recall, but that's
because of a practical issue:  it's hard to fold them up into a small
volume for transportation.  Blimps -- inflated airships -- are more
attractive at present.  They do have to be quite large, however.
