Narrative:
During approach to ILS runway 10 at bwi with WX at 1/2 mi, visibility 100 ft broken, 200 ft overcast, when cleared for approach by final approach controller from 2000 ft, autoplt started down early and autothrottles oversped by 200 KTS. About this time approach controller started giving turns to 2 aircraft behind and above us. One of the aircraft had taken a wrong turn and came close to the other one. Controller was trying to find out what went wrong and did not switch our flight to tower. We were trying to stay on approach after autoplt started down early -- thus, breaking out at minimums and observing the aircraft ahead of us clear of the runway. We landed without talking to tower.

Title: MLG ACFT ON APCH TO MINIMUM WX CONDITIONS FAILED TO CONTACT TWR FOR LNDG CLRNC. APCH CTLR FORGOT TO SWITCH THEM DUE TO HVY WORKLOAD WITH OTHER ACFT SEPARATION PROB.
Narrative: DURING APCH TO ILS RWY 10 AT BWI WITH WX AT 1/2 MI, VISIBILITY 100 FT BROKEN, 200 FT OVCST, WHEN CLRED FOR APCH BY FINAL APCH CTLR FROM 2000 FT, AUTOPLT STARTED DOWN EARLY AND AUTOTHROTTLES OVERSPED BY 200 KTS. ABOUT THIS TIME APCH CTLR STARTED GIVING TURNS TO 2 ACFT BEHIND AND ABOVE US. ONE OF THE ACFT HAD TAKEN A WRONG TURN AND CAME CLOSE TO THE OTHER ONE. CTLR WAS TRYING TO FIND OUT WHAT WENT WRONG AND DID NOT SWITCH OUR FLT TO TWR. WE WERE TRYING TO STAY ON APCH AFTER AUTOPLT STARTED DOWN EARLY -- THUS, BREAKING OUT AT MINIMUMS AND OBSERVING THE ACFT AHEAD OF US CLR OF THE RWY. WE LANDED WITHOUT TALKING TO TWR.
