Wings of iron, nerves of steel Star fuel burns inside its keel Plates of chrome and ruby eyes Terror soars and rules the skies Beak of nickel, claws of tin Built for war, designed to win Bringer of the machine age Vessel with a gilded cage Tipped with many spears of zinc Filled with gas so it won't sink The last member of this line Shall molt its plumes, start to shine A new leader takes the reins Bound no more by any chains All shall bless, join in refrain Piece of a dove, piece of crane.
