Los Angeles, Calif. ---UPI---Edwina MacKenzie, 92, the oldest living survivor of the Titanic, looked over a 10 foot working model of the “unsinkable” ocean liner, which went down in the North Atlantic 65 years ago Friday after striking an iceberg on its maiden voyage. Mrs. MacKenzie still can remember almost every minute of that night when only 790 persons of the 2,307 aboard were saved. Mrs. MacKenzie lives alone in a small house in Hermosa Beach, Calif., still drives a car, has outlasted three husbands and has sailed the Atlantic 10 times since the 1912 tragedy.
