Auroras with their advanced sensor might be an issue though....
Maybe, but what would they detect on a scan, really? A terran fighter with a human pilot in it. Major repairs on the hull probably, a bit makeshift, but who knows what the poor fellow has gone through.
The real problem for this kind of mission would be the IFF, because you'd need to imitate some real unit (preferably one that was shot down, but is listed as MIA). That and chit-chat between pilots, 'cause whoever's infiltrating wouldn't really know the internal stuff on "his" base-ship.
So, in the end it would be best to stay clear of enemy fighters, but there would be no need for 2 kilometers between you and them just because they would scan you.
