The Navy blimp L-8, put out earlier that day in search of Japanese submarines, coasted into Daly California without its crew.
The blimp and its crew of two had taken off at 06:03 from Treasure Island off of San Francisco. At 07:38 its crew radioed that they had seen an oil slick off of Farallon Islands, Point Reyes. A Liberty ship and a fishing boat both later reported that the blimp descended to about 30 feet above the slick and then headed east, rather than its planned route, which would have taken it northwest. It was next spotted at 11:15 off of Ocean Beach, by which time it lacked a crew. The blimp contained its parachutes and life raft, so the crew had not bailed out.
They've never been found.
Official speculation is that they were trying to deploy a smoke signal when one slipped out and the other went to rescue him, with both going into the ocean, or some variant of that. This seems fairly likely, although other theories abound.
The 101st Airborne Division, provided with cadre from the 82nd Airborne Division, was activated. The 82nd had been converted organizationally from a conventional infantry division to an airborne division the day prior.

The 101st had come into the table of organizations during World War One, but just existed for nine days on the charts, having been created immediately before the end of the war. In contrast, the 82nd "All American" Division had seen action in World War One and included in its ranks the famous Alvin York.

The USS Alabama was commissioned.
The Alabama in 1942.
The ship avoided being scrapped in 1964, which the Navy intended to do, and was acquired by the State of Alabama where she became a museum ship. In spite of the original scrapping intent, a provision of the Navy's transfer of her ownership was that she could be recalled if needed, and in fact when the Iowa Class battleships were reactivated in the 1980s, some of her engine parts were cannibalized by the Navy as they were needed for those ships and were no longer manufactured.
The German Navy began Operation Wunderland with the goal of entering the Kara Sea, an extension of the Arctic Ocean, in order to attack Soviet ships that took refuge in the region which was iced up ten months out of the year. The German Navy also sank three ships off of Aracaju, Brazil, operating under the belief that Allied ships were operating in neutral territorial waters off of eastern South America.
