On Jan. 23, 1968, the USS Pueblo, a Navy intelligence-gathering ship, was captured by North Korea....

The ship remained in North Korea, which eventually docked it near Pyongyang, and turned it into a tourist attraction. Visitors can take a tour of the ship, and then watch a 20-minute video officials filmed of the North Korean view of the capture.

But now the Pueblo is missing, NKNews.org. reports. A tour company, Koryo Tours, discovered the disappearance after employees returned from a trip. There is evidence the ship was in place on the Taedong River recently.
