Isn't it strange how the smallest thing can cause the greatest trouble? The old saying goes For lack of a nail, the shoe was lost. For lack of a shoe the horse was lost. For lack of a horse the rider was lost. For lack of the rider, the battle was lost, all for the lack of a nail. Or something like that.
I mourn those seven adventuresome astronauts who accepted the challenge and set their faces toward space. I admire their courage and their intestinal fortitude. May God Almighty be with their families as the world remembers that long ago explosion.
