Narrative:

During landing rollout, by the first officer, taxiway T was taken and the aircraft control was xferred to the captain below 60 KTS. The captain continued the taxi and we crossed runway 28L. As we crossed, neither of us could remember whether tower had cleared us to cross. We had visually checked the final and also knew that runway 28L was closed, so no conflict occurred. We are still not sure if we received a clearance. Cause: during the approach phase of flight, we were vectored in tight and held high for noise abatement (given altitude restr). This made for a challenging approach. I believe that we were both preoccupied with the preceding approach events and this resulted in a lack of attention during the taxiing of the aircraft, resulting in a potential conflict as we crossed the closed runway 28L. A 'hold short of runway 28L' call from tower might have helped. Prevention: pay attention to each phase of flight.

Title: MLG CREW MAY NOT HAVE HAD CLRNC TO CROSS RWY 28L IN SFO.

Narrative: DURING LNDG ROLLOUT, BY THE FO, TXWY T WAS TAKEN AND THE ACFT CTL WAS XFERRED TO THE CAPT BELOW 60 KTS. THE CAPT CONTINUED THE TAXI AND WE CROSSED RWY 28L. AS WE CROSSED, NEITHER OF US COULD REMEMBER WHETHER TWR HAD CLRED US TO CROSS. WE HAD VISUALLY CHKED THE FINAL AND ALSO KNEW THAT RWY 28L WAS CLOSED, SO NO CONFLICT OCCURRED. WE ARE STILL NOT SURE IF WE RECEIVED A CLRNC. CAUSE: DURING THE APCH PHASE OF FLT, WE WERE VECTORED IN TIGHT AND HELD HIGH FOR NOISE ABATEMENT (GIVEN ALT RESTR). THIS MADE FOR A CHALLENGING APCH. I BELIEVE THAT WE WERE BOTH PREOCCUPIED WITH THE PRECEDING APCH EVENTS AND THIS RESULTED IN A LACK OF ATTN DURING THE TAXIING OF THE ACFT, RESULTING IN A POTENTIAL CONFLICT AS WE CROSSED THE CLOSED RWY 28L. A 'HOLD SHORT OF RWY 28L' CALL FROM TWR MIGHT HAVE HELPED. PREVENTION: PAY ATTN TO EACH PHASE OF FLT.
