BBC News, quoting the (shorebound) captain of a robot ship…

“I could foresee a situation where you have a master mariner who’s in charge of a vessel remotely or a number of vessels remotely. Obviously that needs legislation change and part of what we’re building up here is the knowledge and safety case. We send probes and satellites to the other side of the Solar System, so this can be done.”

…Yes: but if a space probe hits a flying saucer, there’s hardly any chance of being sued in court for it.
