Tomorrow is the 21st anniversary of the explosion of STS-51L moments after launch, and the loss of Space Shuttle Challenger and her crew.
And in just a few days, on February 1st, the fourth anniversary of the loss on re-entry of the Space Shuttle Columbia and her crew.
"We will never forget them, nor the last time we saw them, as they prepared for their journey and waved good-bye, and slipped the surly bonds of Earth to touch the face of God."
-- Ronald Reagan, quoting John Gillespie Magee, Jr.
