BOEING 747-300 (N124KK)

KSFO - 28L arrival for the Singapore 747-3 as the fog held off this day as the late PM sun angle from the west glints off San Bruno Mountain to the north. The photo late 1980s or early 90s. I super enlarged this photo to read the reg, showed as N124 but I couldn't read the letters, assuming KK. 1000mm Celestron lens - Minolta XD-11 from the dirt lots before Bayfront Park was built.
