Narrative:

Air carrier X was cleared to land on runway 28R shortly after contacting sfo tower at brijj. Air carrier Y, widebody transport, was then cleared for takeoff on runway 28R. Air carrier Y took a long time to begin the takeoff roll. Meanwhile the crew briefly mentioned wake turbulence techniques. On very short final, the crew lost track of the air carrier Y due to it being at the far end of the runway. Just as the aircraft touched down, tower instructed air carrier X 'go around.' the air carrier Y had aborted the takeoff and was rolling out at the far end of runway 28R. Air carrier Y had not declared an aborted takeoff. At this point it was too late for a balked landing so the captain slowed the aircraft and turned off at taxiway east. The landing was on centerline and in the touchdown zone. On contacting ground control, the crew was instructed to call tower on the phone. When the captain called, the tower supervisor said he had listened to the tapes and asked why we had not gone around. The captain said that the aircraft was on the ground when tower said 'go around' and to go around would have required a touch- and-go toward an aircraft on the runway. Contributing factors: light winds not clearing exhaust smoke. When air carrier X crew first saw air carrier Y, only the top half of the vertical fin was visible. The rest of the aircraft was completely obscured.

Title: ACR X LANDED ON OCCUPIED RWY AFTER ACR Y ABORTED TKOF. RWY INCURSION.

Narrative: ACR X WAS CLRED TO LAND ON RWY 28R SHORTLY AFTER CONTACTING SFO TWR AT BRIJJ. ACR Y, WDB, WAS THEN CLRED FOR TKOF ON RWY 28R. ACR Y TOOK A LONG TIME TO BEGIN THE TKOF ROLL. MEANWHILE THE CREW BRIEFLY MENTIONED WAKE TURB TECHNIQUES. ON VERY SHORT FINAL, THE CREW LOST TRACK OF THE ACR Y DUE TO IT BEING AT THE FAR END OF THE RWY. JUST AS THE ACFT TOUCHED DOWN, TWR INSTRUCTED ACR X 'GAR.' THE ACR Y HAD ABORTED THE TKOF AND WAS ROLLING OUT AT THE FAR END OF RWY 28R. ACR Y HAD NOT DECLARED AN ABORTED TKOF. AT THIS POINT IT WAS TOO LATE FOR A BALKED LNDG SO THE CAPT SLOWED THE ACFT AND TURNED OFF AT TXWY E. THE LNDG WAS ON CTRLINE AND IN THE TOUCHDOWN ZONE. ON CONTACTING GND CTL, THE CREW WAS INSTRUCTED TO CALL TWR ON THE PHONE. WHEN THE CAPT CALLED, THE TWR SUPVR SAID HE HAD LISTENED TO THE TAPES AND ASKED WHY WE HAD NOT GONE AROUND. THE CAPT SAID THAT THE ACFT WAS ON THE GND WHEN TWR SAID 'GAR' AND TO GAR WOULD HAVE REQUIRED A TOUCH- AND-GO TOWARD AN ACFT ON THE RWY. CONTRIBUTING FACTORS: LIGHT WINDS NOT CLRING EXHAUST SMOKE. WHEN ACR X CREW FIRST SAW ACR Y, ONLY THE TOP HALF OF THE VERT FIN WAS VISIBLE. THE REST OF THE ACFT WAS COMPLETELY OBSCURED.
