Narrative:
On nov/mon/03, I was captain on air carrier X sfo-san. We were taxiing east on taxiway B approaching taxiway T. I saw an air carrier Y brasilia turning toward us at high speed on taxiway T. I turned right 8-10 ft right off centerline, turned on all of my lights and stopped. My first officer verbalized the threat to me. A second air carrier Z brasilia pulled into taxiway T right behind air carrier Y. Sfo ground, south ground, told us to move. I told my first officer to tell south ground we cannot move. Air carrier Y told us we had 30 ft clearance. I looked at the mark on my left sliding window and determined that my left wing would pass over the offending aircraft. South ground told us to move. I got on the radio and announced with special emphasis, 'I am the captain and we are not moving!' south ground told us that he would have to send a B747 around on runway 28L. My excellent first officer told the controller, 'what don't you understand! We aren't moving!' sfo tower sent the B747 around. South ground told air carrier Z to do a 180 degrees, back taxi to taxiway D and exit runway 28L. South ground told air carrier Y to do the same. Many ATC communications took place. My first officer asked if we could proceed. South ground told us to continue to runway 1L. After takeoff, departure told us to call sfo tower on landing. That night, there was very little traffic. Normally south ground clears you via taxiway a to taxiway F, then taxiway B to runway 1L. I don't know why we were given taxiway B that night, but that was the cause of the near ground collision. With all of the high speed txwys off of runway 28L, it is not smart to use taxiway B for outbound traffic. I called an sfo supervisor. We discussed the situation. I told him how I determined the separation issue. He understood. We both discussed how important safety was and how it was better to stop. He told me that the issue was dead at that point.

Title: A B757 TAXIING OUT FOR TKOF SFO RWY 1 BECOMES HEAD ON WITH 2 BRASILIA EXITING THE RWY. THE SECOND BRASILIA WAS NOT COMPLETELY CLR OF THE RWY RESULTING IN A GAR BY A B747.
Narrative: ON NOV/MON/03, I WAS CAPT ON ACR X SFO-SAN. WE WERE TAXIING E ON TXWY B APCHING TXWY T. I SAW AN ACR Y BRASILIA TURNING TOWARD US AT HIGH SPD ON TXWY T. I TURNED R 8-10 FT R OFF CTRLINE, TURNED ON ALL OF MY LIGHTS AND STOPPED. MY FO VERBALIZED THE THREAT TO ME. A SECOND ACR Z BRASILIA PULLED INTO TXWY T RIGHT BEHIND ACR Y. SFO GND, S GND, TOLD US TO MOVE. I TOLD MY FO TO TELL S GND WE CANNOT MOVE. ACR Y TOLD US WE HAD 30 FT CLRNC. I LOOKED AT THE MARK ON MY L SLIDING WINDOW AND DETERMINED THAT MY L WING WOULD PASS OVER THE OFFENDING ACFT. S GND TOLD US TO MOVE. I GOT ON THE RADIO AND ANNOUNCED WITH SPECIAL EMPHASIS, 'I AM THE CAPT AND WE ARE NOT MOVING!' S GND TOLD US THAT HE WOULD HAVE TO SEND A B747 AROUND ON RWY 28L. MY EXCELLENT FO TOLD THE CTLR, 'WHAT DON'T YOU UNDERSTAND! WE AREN'T MOVING!' SFO TWR SENT THE B747 AROUND. S GND TOLD ACR Z TO DO A 180 DEGS, BACK TAXI TO TXWY D AND EXIT RWY 28L. S GND TOLD ACR Y TO DO THE SAME. MANY ATC COMS TOOK PLACE. MY FO ASKED IF WE COULD PROCEED. S GND TOLD US TO CONTINUE TO RWY 1L. AFTER TKOF, DEP TOLD US TO CALL SFO TWR ON LNDG. THAT NIGHT, THERE WAS VERY LITTLE TFC. NORMALLY S GND CLRS YOU VIA TXWY A TO TXWY F, THEN TXWY B TO RWY 1L. I DON'T KNOW WHY WE WERE GIVEN TXWY B THAT NIGHT, BUT THAT WAS THE CAUSE OF THE NEAR GND COLLISION. WITH ALL OF THE HIGH SPD TXWYS OFF OF RWY 28L, IT IS NOT SMART TO USE TXWY B FOR OUTBOUND TFC. I CALLED AN SFO SUPVR. WE DISCUSSED THE SIT. I TOLD HIM HOW I DETERMINED THE SEPARATION ISSUE. HE UNDERSTOOD. WE BOTH DISCUSSED HOW IMPORTANT SAFETY WAS AND HOW IT WAS BETTER TO STOP. HE TOLD ME THAT THE ISSUE WAS DEAD AT THAT POINT.
