On "slipping the surly bonds of earth"

In memory of the Challenger disaster, here is the Text of Reagan's beautiful speech,  posted by The American Presidency Project, and originally penned by Peggy Noonan (if you want a good political read, try What I Saw at the Revolution).

Here is a Washington Post article about the speech: Exactly the Right Words

Here is the text of the poem which inspired the quote used at the end of the speech, posted at Arlington Cemetery's website: High Flight by John Gillespie Magee.
