Milestones

DIED. Jack Armstrong, 74, the real (though Canadian-born) All-American Boy whose name was used for the boldhearted teenage radio hero of the '30s and '40s and who himself went on to become a worthy, if merely life-size, embodiment of his plucky namesake, serving as a much decorated U.S. Air Force officer and helping to oversee the development of atomic-powered satellites; in Laguna Niguel, Calif. The radio serial, which was largely sponsored by Wheaties, got the name for the fictional stalwart of Hudson High from a General Mills executive who had been a college fraternity brother of Armstrong's.
