Narrative:

We were cleared to land on runway 27 san at least 5 mi out. About 2 mi out I noticed an medium large transport crossing the hold lines at the approach end of runway 27 and taxiing onto the runway. I pointed it out to my copilot. We waited to see what would happen. The jet was moving too slowly to be lined up and ready to go before we got there. At about 3/4 mi to the field, I called the tower and said, 'do you want us, X, to go around?' the tower replied, 'no X, you are cleared to...X, go around.' 'medium large transport, you were told to hold short of the runway; taxi into position and hold.' medium large transport did not reply. We overflew the aircraft on the runway at about 500'. I called the tower after we landed and he confirmed the medium large transport did not have a clearance to be on the runway.
