Narrative:

Was holding short of runway 29L on taxiway C, waiting for clearance to cross. I heard what sounded like a clearance to taxi and acknowledged to that effect. My acknowledgement was apparently blocked and we heard no further reply, thereby assuming we were cleared. Conflict, I was told, was another aircraft was in the flare for landing on that runway. This report should have been filed on my part some time ago, but have not been home. Thus, I realize this may be invalid, but will submit anyway.
