This photo shows U.S. diplomat Henry W. Antheil Jr. dated 1940. The 27-year-old Antheil was one of the nine people aboard the Finnish Junkers Ju 52 passenger airliner named Kaleva that was shot down over the Baltic Sea by Soviet bombers on June 14, 1940. The plane was en route from the Estonian capital, Tallinn, to Helsinki when it was downed just days before Moscow annexed the Baltic states. All nine people aboard Finnish aircraft died. Antheil, the younger brother of acclaimed composer George Antheil, is considered to be among the first U.S. casualties of World War II. (Library of Congress via AP)
