When I was a ten years old, I had a toy I took with me everywhere. It was a model I had made. Even though I was on the edge of being to old for such things, I would play with it. Especially in the car. I would make it fly and land, fly and land.
That toy was a replica of the Space Shuttle. It had the name "Columbia" affixed as a sticker on both sides of the hull.
Five years ago today, Columbia went down over my home state of Texas. Over Nacogdoches, aka "Nac-a-nowhere" to my friends who lived there.
To me, the Columbia represented adventure, exploration, and curiosity. I remember where I was when the Challenger exploded. And I remember where I was when Columbia blew apart.
Today I remember them both, and what they meant to me.
