A window washer fell about 11 stories from the top of the Sterling Bank and Trust building in San Francisco Friday, landing on a car in the middle of a busy street.

San Francisco Police Lt. Ed Del Carlo said the worker was getting ready to work when he "fell off the apparatus" and landed on a green Camry about 10 a.m. from the building at 400 Montgomery Street, near the intersection with California Street.

The driver, who wasn't injured, "didn't know what happened," Del Carlo said.

The window washer was taken to the hospital. Del Carlo said the worker's condition appeared critical, with a possible compound fracture and other injuries. He was with a partner, who was not hurt. Julia Bernstein, a spokeswoman for Cal-OSHA, said a safety engineer was on scene, trying to determine what happened.
