First heard his voice during Saturday morning cartoons-- made a huge impression on me and made the segments very watchable.
Good work, sir. Take your rest.
I will never forget his voice on Jan 28, 1986. I was at work and could not watch the space shuttle launch on TV so I had to rely on radio. You could hear the excitement in Glenn's voice when he said "Christa McAuliffe is on her way!" moments after liftoff. Then a few seconds later CBS concluded their coverage and went off the air, before the catastrophe occurred. When a coworker told me a few minutes later there was "some kind of explosion" I turned my radio back on. The first thing I heard was Christopher Glenn again. A powerful, sad day.
