Narrative

ON THE MORNING OF OCT/TUE/05; I WAS ASKED TO MOVE ACFT X FROM 'C' CONCOURSE TO THE HANGAR. I STARTED THE ENGS AND HEARD RAMP CTL SAY TO PROCEED TO SPOT. I PROCEEDED TO WHAT I THOUGHT WAS THE SPOT. WHILE APCHING THE SPOT; I HEARD MR X CONTACT GND. RAMP TOLD MR X TO CONTACT GND. WE WERE ON POINT X; SO I ADJUSTED TO POINT Y. DURING TAXI OUT; THE COCKPIT WAS COLD; SO MR X WAS ADJUSTING AIR TO HOT; BUT WE WERE DISCUSSING THAT COCKPIT WASN'T GETTING HOT; AIR WAS BLOWING COLD. I THOUGHT I HEARD GND SAY 'CROSS RWY AT BRAVO.' AN ACFT WAS PASSING BY FROM LNDG ON RWY. AFTER PASSING; I LOOKED BOTH WAYS AND PROCEEDED FORWARD. AS I WAS MOVING FORWARD; I ASKED MR X 'ARE WE ON 'B?' AND HE SAID 'YES; GO AHEAD.' I STARTED FORWARD AND CROSSED THE LINE AND REALIZED I WAS NOT ON 'B'; BUT 'G.' I COULD NOT TURN AROUND; SO I KEPT ON GOING. I WAS DISCUSSING WITH MR X THAT WE CROSSED AT 'G' INSTEAD OF 'B.' WE PROCEEDED TO THE HANGAR AND PARKED THE ACFT. GND CTL SAID ON THE RECORDING TO HOLD SHORT OF RWY 5/23 AT TXWY B AND THOUGHT CROSS RWY 5/23 AT TXWY B. I SHOULD HAVE PAID ATTN TO THE RADIO COMMAND BETTER; AND IF ANY QUESTIONS; I SHOULD HAVE ASKED.
