A ferry worker dove into the water and helped the family escape, getting the fourth person out of the minivan just seconds before it sank 15 feet into Newport Harbor.
Witnesses said the family remained calm throughout the ordeal.

"Kids were sitting there playing on the phone," said witness Matt Reed. "The mom and dad were sitting there looking around. They were completely calm."
No one was hurt -- the van went under just after the final passenger was rescued.
In addition to the ferry worker who led the rescue effort, two boaters pulled alongside to help.
Witnesses said a black Mercedes-Benz accidentally accelerated as it boarded the ferry. It rammed the minivan, pushing it into the water. Deputies said the driver would not be cited.
The Mercedes was also left teetering off the end of the ferry, but workers were able to keep it from following the minivan into the harbor.
The incident occurred shortly after 9 a.m. on the Balboa Island side of the ferry run.
Witnesses also said the minivan floated for about a minute and a half before it sank.
