Narrative:

Upon arrival in sfo; we found one air traffic controller handling all aircraft movements on the field (ground and tower); as stated by the controller himself. Sfo was as busy as I've ever seen it; and for one person to handle push back and taxi requests; as well as arrivals and departures on crossing runways; at night; was absolutely ridiculous. This was the biggest safety threat I've seen in a long time. Additional factors included three-hour delays that all aircraft were experiencing; operations in the middle of the night; with enormous amounts of construction occurring across the airport (and the resulting runway and taxiway closures); made this an accident waiting to happen. The tower should have been fully staffed for an evening like this.
