I remember what I was doing seventeen years ago because of a terrible tradegy. Now I have another tradegy to remember. I guess it won't compare to 9-11, but I think I'll always remember that I was home when I turned on CNN and they had that "Breaking News" logo and my heart just sank. Columbia was gone. My heart goes out to the families but I'm sure they would agree with me that space exploration must continue. One day this earth will no longer be big enough to hold all of humanity and the only way we can grow is up and out.
