It doesn't seem possible that it's been thirty years. I was 15 years old and had just gotten home from school, turned on the TV and saw that the Space Shuttle had broken apart. I cried watching the newscast. As I often did during that time of my life, I turned to music to try and cope with the tragedies that we're often unequipped to deal with. About a year before I had gotten in to Rush and had recently picked up
Signals. It contained the song 'Countdown', which celebrates the US space program and is a chronicle of a shuttle launch.
Rush - Countdown
I've never been able to hear it since without thinking of the Challenger.
