Narrative:

Sfo tipp toe approach at night, 2 widebody transport's involved, both same company. Approach cleared both of us for a visibility approach to maintain visibility sep from each other. Air carrier X landing on runway 28L. Air carrier Y was on the quiet bridge approach. We both had the same visibility approach clearance. Air carrier X was in front, air carrier Y was very slightly behind. He passed us on the approach due to speed difference. Captain of air carrier X was forced to communicate with air carrier Y to establish landing sep because approach control failed to provide any sep or control of either aircraft's approach. This has been, and continues to be, the single most dangers evolution our pilots routinely perform. The question of disaster is not 'whether,' but 'when.'

Title: SIDE BY SIDE VISUAL APCHS SFO.

Narrative: SFO TIPP TOE APCH AT NIGHT, 2 WDB'S INVOLVED, BOTH SAME COMPANY. APCH CLRED BOTH OF US FOR A VIS APCH TO MAINTAIN VIS SEP FROM EACH OTHER. ACR X LNDG ON RWY 28L. ACR Y WAS ON THE QUIET BRIDGE APCH. WE BOTH HAD THE SAME VIS APCH CLRNC. ACR X WAS IN FRONT, ACR Y WAS VERY SLIGHTLY BEHIND. HE PASSED US ON THE APCH DUE TO SPD DIFFERENCE. CAPT OF ACR X WAS FORCED TO COMMUNICATE WITH ACR Y TO ESTABLISH LNDG SEP BECAUSE APCH CTL FAILED TO PROVIDE ANY SEP OR CTL OF EITHER ACFT'S APCH. THIS HAS BEEN, AND CONTINUES TO BE, THE SINGLE MOST DANGERS EVOLUTION OUR PLTS ROUTINELY PERFORM. THE QUESTION OF DISASTER IS NOT 'WHETHER,' BUT 'WHEN.'
