A memorial to 10 American airmen whose plane was shot down off the coast of Latvia was unveiled April 8 in Liepāja.

The plane was shot down April 8, 1950, by the Soviet military. What happened to the crew,however, is unclear. Some reports suggest that eight of the airmen survived and were kept as prisoners by the Soviets, according to an Associated Press story.

American military personnel and the U.S. ambassador to Latvia, James Holmes, attended the dedication ceremony, according to the Liepāja newspaper Kurzemes Vārds.
