His early years in broadcasting were spent working for the American Forces Network while he served in the United States Army in 1960.
Glenn made his best-known report on January 28, 1986, when he anchored CBS News Radio's live coverage of the launch of the Space Shuttle Challenger.
Glenn had just signed off—after what was thought to have been a normal launch—when the shuttle disintegrated, killing the seven astronauts on board.
Glenn continued to play sound clips in his newscasts from carts long after most of the industry had switched to computer-based playback systems.
[3] Glenn, who suffered from liver cancer, died suddenly on October 17, 2006 at the age of 68 in Norwalk, Connecticut.
