The poem "Cape Hatteras" by Hart Crane in the collection "The Bridge" stood out to me as the poet trying to come to grips with several large changes in his society.  The main change mentioned was the invention of the airplane.  Crane's poem serves as a bridge between the idealized past and the present.  He seems almost resentful of the Wright brothers success, asking the then dead writer Walt Whitman "if infinity be still the same as when you walked the beach" (lines 48-49).  The implication is that inventions such as the airplane are destroying the wonder and grandeur of the world by making it easier to travel.  He longs for the older idea of the world, that the heavens are infinite.  On line 32 he writes "But that star-glistered salver of infinity, The circle, blind crucible of endless space, Is sluiced by motion,-subjugated never".  He notes how machinery has subjugated the rest of the world, mentioning dynamos humming, belts on spool feeding machines slapping, flywheels in motion, and other machines that he refers to as "steely gizzards" (line 75).  As the poem progresses, he offers another complaint of technology, particularly the airplane, that it would be used in war. 
He writes  "Hell's belt springs wider into heaven's plumed side" (line 96), suggesting that the airplane was corrupted for its role as a weapon of war.  Later, to make it a bit more clear, he says "Tellurian wind-sleuths on dawn patrol, Each plane a hurtling javelin of winged ordnance, Bristle the heights above a screeching gale to hover" (lines 107-109).  Crane stands on a bridge between past and present, far preferring to be of the side of the past rather than the present.
