Narwhal's Passenger from Mindanao

Narwhal (SS-167) Built in 1930, the USS Narwhal was one of the oldest submarines in service. Her loyal crew was proud of her although she was bulkier and slower than her more modern sisters. A quirk in her diving mechanism had given the Narwhal the reputation of being haunted. Under attack by Japanese bombers while engaged in a rescue operation, her skipper defied her shortcomings and put the sub through some agonizing paces. It plunged straight for the bottom. How the Narwhal managed to escape disaster is told in this episode of "The Silent Service".
