Tribute to Discovery

I watched the shuttle Discovery land this morning. It's last landing; the beginning of the end of an era. It brought this to mind:

"I pray for one last landing

On the globe that gave me birth;

Let me rest my eyes on the fleecy skies

And the cool, green hills of Earth."

Robert A. Heinlein

I think this would make a fitting addition to the display when Discovery is displayed at the Smithsonian Institution's National Air and Space Museum.
