It's one of those images we as Americans will never be able to shake. "Go with Throttle up" and then the horror. The explosion. The tragedy of Challenger exploding over the crisp blue Florida sky 27 years ago today. Much like my Mom did with President Kennedy did, I remember where I was when I saw the explosion.

I was walking from class to lunch in High School. The A/V department had a TV set up in the hall to watch, since there was a teacher on board. Sally Ride never made it back to her classroom. It was quiet as I had ever heard a school hall be. Even stupid kids who make fun of everything stood dumbfounded.

NASA has a story with the memories of that morning. "Remembering the Challenger Crew"

"The crew of the space shuttle Challenger honored us by the manner in which they lived their lives. We will never forget them, nor the last time we saw them, this morning, as they prepared for the journey and waved goodbye and "slipped the surly bonds of earth" to "touch the face of God."

President Ronald Reagan, January 28th 1986.
