Narrative:
Captain accepted ILS approach clearance approximately 3 NM outside ILS runway 24 FAF to fok. Aircraft was very high above required altitude and very fast (approximately 230 KTS). New york approach asked crew if they would be able to descend to cleared altitude in time to execute the ILS approach and the captain answered affirmatively. In haste to descend, captain flew aircraft below GS inside MM (approximately 3000 FPM descent rate) and drifted left of course off localizer. New york issued a low altitude warning through control tower 2 times. Aircraft was still in heavy mist on approximately 2 1/2 - 3 mi final when first officer asked captain if a go around (missed approach) was going to be executed. First officer then advised captain that a full scale deflection of both the GS and localizer had occurred and called for a missed approach. Captain ignored missed approach call and said she had the airport in sight. First officer did not concur but captain executed visual approach anyway and rolled out on final with both VASI lights red and GPWS activated. Tower inquired if everything was all right and cleared aircraft to land.

Title: A GULFSTREAM 4 CAPT COMPLETED AN UNSTABILIZED APCH WITH A NEAR CFIT AGAINST THE FO'S OBJECTIONS AT FOK.
Narrative: CAPT ACCEPTED ILS APCH CLRNC APPROX 3 NM OUTSIDE ILS RWY 24 FAF TO FOK. ACFT WAS VERY HIGH ABOVE REQUIRED ALT AND VERY FAST (APPROX 230 KTS). NEW YORK APCH ASKED CREW IF THEY WOULD BE ABLE TO DSND TO CLRED ALT IN TIME TO EXECUTE THE ILS APCH AND THE CAPT ANSWERED AFFIRMATIVELY. IN HASTE TO DSND, CAPT FLEW ACFT BELOW GS INSIDE MM (APPROX 3000 FPM DSCNT RATE) AND DRIFTED L OF COURSE OFF LOC. NEW YORK ISSUED A LOW ALT WARNING THROUGH CTL TWR 2 TIMES. ACFT WAS STILL IN HVY MIST ON APPROX 2 1/2 - 3 MI FINAL WHEN FO ASKED CAPT IF A GAR (MISSED APCH) WAS GOING TO BE EXECUTED. FO THEN ADVISED CAPT THAT A FULL SCALE DEFLECTION OF BOTH THE GS AND LOC HAD OCCURRED AND CALLED FOR A MISSED APCH. CAPT IGNORED MISSED APCH CALL AND SAID SHE HAD THE ARPT IN SIGHT. FO DID NOT CONCUR BUT CAPT EXECUTED VISUAL APCH ANYWAY AND ROLLED OUT ON FINAL WITH BOTH VASI LIGHTS RED AND GPWS ACTIVATED. TWR INQUIRED IF EVERYTHING WAS ALL RIGHT AND CLRED ACFT TO LAND.
