Narrative:

We were on a macey 2 arrival into atl. Approach initially gave us runway 8L and then changed it to runway 9R. Because of other traffic, approach had to keep us high on the arrival. It was a visual approach backed up with the ILS. Approach gave us the traffic we were following. We acknowledged and they gave us a short approach turning us in close for landing. We were comfortable with the approach but because of the flight parameters we were busy complying. We believe that approach did not clear us over to tower. This is not an excuse, we should have switched to tower on our own. On top of this, at about 1200 ft AGL, we thought we saw a small aircraft on the runway in position for takeoff, but as we got in closer we realized it was an illusion created by runway markings and rubber marks. We landed without landing clearance. There were no potential conflicts or any other safety issues. I believe the error was caused by: 1) a busy approach. 2) approach not changing us to tower. 3) we did not go to tower on our own. 4) confusion about aircraft on the runway.

Title: FLC OF A B757 FORGOT TO CONTACT THE TWR AND LANDED WITHOUT CLRNC. FLC WERE DISTR DUE TO BEING POSITIONED BY APCH CTL IN A HIGH CLOSE IN POS. IN ADDITION, APCH DID NOT ADVISE RPTR TO CONTACT TWR.

Narrative: WE WERE ON A MACEY 2 ARR INTO ATL. APCH INITIALLY GAVE US RWY 8L AND THEN CHANGED IT TO RWY 9R. BECAUSE OF OTHER TFC, APCH HAD TO KEEP US HIGH ON THE ARR. IT WAS A VISUAL APCH BACKED UP WITH THE ILS. APCH GAVE US THE TFC WE WERE FOLLOWING. WE ACKNOWLEDGED AND THEY GAVE US A SHORT APCH TURNING US IN CLOSE FOR LNDG. WE WERE COMFORTABLE WITH THE APCH BUT BECAUSE OF THE FLT PARAMETERS WE WERE BUSY COMPLYING. WE BELIEVE THAT APCH DID NOT CLR US OVER TO TWR. THIS IS NOT AN EXCUSE, WE SHOULD HAVE SWITCHED TO TWR ON OUR OWN. ON TOP OF THIS, AT ABOUT 1200 FT AGL, WE THOUGHT WE SAW A SMALL ACFT ON THE RWY IN POS FOR TKOF, BUT AS WE GOT IN CLOSER WE REALIZED IT WAS AN ILLUSION CREATED BY RWY MARKINGS AND RUBBER MARKS. WE LANDED WITHOUT LNDG CLRNC. THERE WERE NO POTENTIAL CONFLICTS OR ANY OTHER SAFETY ISSUES. I BELIEVE THE ERROR WAS CAUSED BY: 1) A BUSY APCH. 2) APCH NOT CHANGING US TO TWR. 3) WE DID NOT GO TO TWR ON OUR OWN. 4) CONFUSION ABOUT ACFT ON THE RWY.
