The driver of a Ford Fiesta was heading down Vista Way around 8 p.m. Wednesday when he lost control of the car. The car left the roadway and slammed broadside into a palm in a grassy median separating the road from a parking lot.
Three Marines were at a nearby Applebee's when they heard the crash and jumped into action. They wrenched the windshield from the vehicle to get a passenger out of the car and then worked to free the driver until paramedics arrived and took over.
Two of the victims had to be airlifted to hospitals in La Jolla. The other victim was taken by ambulance to Tri City Medical Center.
Police were trying to determine the cause of the single-car crash. It was not immediately known if drugs or alcohol were a factor.
