> small claims court (I’m not joking they don’t even care about that)

If they don't show up, doesn't that mean you win by default? (And then you can indeed send a bailiff to seize a plane...)

Depending on the jurisdiction, getting a judgement alone doesn't allow you to have a bailiff enforce it.

Yes, you can win in small claims if the other party doesn't show. I suspect a plane might exceed the "small claims" limit though!
