Space Shuttle Challenger Accident: A 30-year anniversary

Yesterday was the 30th anniversary of the explosion of the Space Shuttle Challenger.  Its destruction a little over a minute after liftoff resulted in the death of all seven members of Challenger's crew, and was followed by an intensive investigation into the disaster's causes.

This C-SPAN video (6:44) shows Challenger's liftoff and explosion, and President Reagan's address to the nation later that night.

In this memorable last sentence, President Reagan ended his short remarks by discussing the Challenger's crew:

We will never forget them, nor the last time we saw them, this morning, as they prepared for their journey and waved goodbye and "slipped the surly bonds of earth" to "touch the face of God."
