Two elderly women drove off a cliff in Point Defiance Park on Thursday and had to be rescued. Witnesses called 911 about 12:30 p.m. to report seeing a car drive through a fence and over an embankment at a viewpoint off Five Mile Drive on the northwestern side of the Tacoma park. The car came to rest about 150 feet down a steep hill. A Tacoma Fire rescue team rappelled down the cliff to free the driver and passenger, who were pulled out of the wreckage about 1:40 p.m. They were carried down to the water and placed on to a Tacoma Fire boat. Once onshore, the two were taken to an area hospital. The women were in serious but stable condition after the rescue, Tacoma Fire spokesman Joe Meinecke said.
