Narrative:

We were on stabilized ILS to runway 25L. An air carrier medium large transport Y visibility approach to lax for the north runways (not the south), overflew the final approach course and came directly overhead our air carrier large transport X on approach for the southern most runway at lax. Tower was slow to respond. Had air carrier medium large transport Y descended any more for the wrong runway, we all would have had a serious problem.

Title: NMAC BETWEEN TWO ACR ACFT AT LAX.

Narrative: WE WERE ON STABILIZED ILS TO RWY 25L. AN ACR MLG Y VIS APCH TO LAX FOR THE N RWYS (NOT THE S), OVERFLEW THE FINAL APCH COURSE AND CAME DIRECTLY OVERHEAD OUR ACR LGT X ON APCH FOR THE SOUTHERN MOST RWY AT LAX. TWR WAS SLOW TO RESPOND. HAD ACR MLG Y DSNDED ANY MORE FOR THE WRONG RWY, WE ALL WOULD HAVE HAD A SERIOUS PROB.
