A sad day in our nation's history

It's not necessarily our worst, or most tragic day, but it still doesn't lessen the impact of the tragedy.

Today's tragedy brings back shadows of the Challenger tragedy in 1986, though that one happened during launch while this one happened during landing.

My heart goes out to the families of the astronauts on the shuttle Columbia. May all 7 of the astronauts RIP...
