Narrative:

We were cleared for a night visibility approach to runway 17R at den. As we crossed the threshold, just prior to T/D, we could see an aircraft who appeared to cross our runway at approximately 3/4 of the way down the runway. We did not hear the tower give him clearance to cross. We went straight across the runway and was almost clear as we made contact with the runway. In my judgement, it was safer to continue the landing at this point than to attempt a go around, since a go around at that point would have resulted in contacting the runway, anyway. After an uneventful landing and rollout, we contacted the tower supervisor upon our arrival at the gate to advise him of the incident.

Title: ACR ON VISUAL NIGHT APCH ENCOUNTERS ACFT CROSSING RWY JUST PRIOR TO TOUCHDOWN.

Narrative: WE WERE CLRED FOR A NIGHT VIS APCH TO RWY 17R AT DEN. AS WE CROSSED THE THRESHOLD, JUST PRIOR TO T/D, WE COULD SEE AN ACFT WHO APPEARED TO CROSS OUR RWY AT APPROX 3/4 OF THE WAY DOWN THE RWY. WE DID NOT HEAR THE TWR GIVE HIM CLRNC TO CROSS. WE WENT STRAIGHT ACROSS THE RWY AND WAS ALMOST CLR AS WE MADE CONTACT WITH THE RWY. IN MY JUDGEMENT, IT WAS SAFER TO CONTINUE THE LNDG AT THIS POINT THAN TO ATTEMPT A GAR, SINCE A GAR AT THAT POINT WOULD HAVE RESULTED IN CONTACTING THE RWY, ANYWAY. AFTER AN UNEVENTFUL LNDG AND ROLLOUT, WE CONTACTED THE TWR SUPVR UPON OUR ARR AT THE GATE TO ADVISE HIM OF THE INCIDENT.
