Breakthrough

O upon skies endless and mystical, run you young aeroplanes, vault over space in vast exuberance, and magical with beauty shine in unexampled grace! High-standing structures, in maternal earth conceived and by men's minds set free, invade the ports of light and in your sheaths stand forth, facing the antique heavens unafraid. Round us the limiting horizons rope off space, the oceans drop an iron rim and all's held back; but I see you escape beyond the distances, even past dream, past even thought. Air parts and Time divides upon your presences; o dazzling forms racing angel-high, only the sun speeds also past sound, the darkness outperforms!
