John McCaslin at the WaPo has one of the last emails from William McCool before Columbia began its fatal descent:

"PS ? As I write, we just experienced a sunset over the Pacific, just [west] of Chile. I'm sitting on the flight deck in the CDR seat (front right) with a view of the Earth moving gracefully by. Sunsets and sunrises from space come every 45 minutes, and last only about 30 seconds, but the colors are stunning. In a single view, I see looking out at the edge of the Earth ? red at the horizon line, blending to orange, then yellow; followed by a thin white line, then light blue, gradually turning to dark blue, then various gradually darker shades of gray, then black with a million stars above. It's breath-taking."

Yet many people still believe that no one would pay for such an experience.

Waiting for NASA to get me into space is like waiting for the DMV to me into a Ferrari.

Why is it that when I read this entry, my first thought was of Derek Lyons?
