Photographs: The featured image above, from the U.S. National Archives, shows L-8 drifting over the San Francisco area on 16 August 1942. A second Navy photo shows the same airship four months earlier, delivering parts to the carrier USS Hornet at sea before the Doolittle Raid (NH 53294 on Wikimedia Commons).

What happened

L-8 was a small, non-rigid airship, one of five Goodyear advertising blimps the Navy took over after Pearl Harbor and flew from Moffett Field and Treasure Island on coastal patrols. According to the Naval History and Heritage Command, it had already done important work: in April 1942 it delivered “vital equipment” to USS Hornet while the carrier was en route to launch the Doolittle Raiders.

On the morning of 16 August 1942, Lieutenant (junior grade) Ernest DeWitt Cody and Ensign Charles Ellis Adams lifted off from Treasure Island at about 6 a.m. on a routine anti-submarine patrol west toward the Farallon Islands.

At about 7:40 a.m. the crew radioed that they were investigating a suspicious oil slick. A fishing boat and a merchant ship in the area later reported seeing the blimp descend low over the water and circle. After that, there was silence. Treasure Island’s calls went unanswered.

At about 11:15 a.m., beachgoers at Ocean Beach watched L-8 drift in from the sea. It bumped the sand, where fishermen grabbed at its lines, lost a depth charge, rose again, and drifted inland over San Francisco, sagging as it lost helium. It finally came down on the 400 block of Bellevue Avenue in Daly City. When rescuers reached the gondola, it was empty. As the Navy’s history puts it, “the control car was empty and the interior was in perfect order.” The lost depth charge was later recovered on a golf course.

What believers claim

Because there was no distress call and no sign of a struggle, the case attracts theories that go well past an accident: that a Japanese submarine captured the crew, that the two men staged a desertion, or that something stranger took them. The “ghost ship” label and the image of an empty airship drifting into a city have made L-8 a fixture of unexplained-mystery lists.

What the research found

The hooks: an airship returns from patrol with its engines and radio intact, parachutes and life raft still aboard, and no crew. Their last message mentions an oil slick, a classic sign of a submarine.
