I've only been going between EA and the ice-ringed planet in the same system. Usually see a few hollow squares around the station, sat and watched somebody in a large ship getting stuck in the letterbox earlier on, but have only ever seen one commander at the planet - I was about to o7 but they jumped out, they must have just been charging their jump as I arrived.
That wouldn't have been me arguing with an incoming Orca, would it? When the station is in the 'dark' a black ship coming in is hard to see, I lasted a couple of seconds before seeing a 14 million rebuy
