Q22:  From what does "I have slipped the surly bonds..." come?

A:                 High Flight

            by John Gillespie Magee, Jr. 

     Oh, I have slipped the surly bonds of earth
     And danced the skies on laughter-silvered wings;
     Sunward I've climbed, and joined the tumbling mirth
     Of sun-split clouds -- and done a hundred things
     You have not dreamed of -- wheeled and soared and swung
     High in the sunlit silence.  Hov'ring there,
     I've chased the shouting wind along, and flung
     My eager craft through footless halls of air.
     Up, up the long, delirious, burning blue
     I've topped the windswept heights with easy grace
     Where never lark, or even eagle flew.
     And, while with silent, lifting mind I've trod
     The high untrespassed sanctity of space,
     Put out my hand, and touched the face of God.
