Famous quotes containing the words plane, waves and/or vacuum:

    Have you ever been up in your plane at night, alone, somewhere, 20,000 feet above the ocean?... Did you ever hear music up there?... It’s the music a man’s spirit sings to his heart, when the earth’s far away and there isn’t any more fear. It’s the high, fine, beautiful sound of an earth-bound creature who grew wings and flew up high and looked straight into the face of the future. And caught, just for an instant, the unbelievable vision of a free man in a free world.
    Dalton Trumbo (1905–1976)

    the whole sea become an entanglement of watery bodies
    lost to the world bearing what they cannot hold. Broken,

    beaten, desolate, reaching from the dead to be taken up
    they cry out, failing, failing! their cries rising
    in waves still as the skillful yachts pass over.
    William Carlos Williams (1883–1963)

    No, it wasn’t an accident, I didn’t say that. It was carefully planned, down to the tiniest mechanical and emotional detail. But it was a mistake. It was a beaut. In the end, somehow granted the time for examination, we shall find that our so-called civilization was gloriously destroyed by a handful of vacuum tubes and transistors. Probably faulty.
    John Paxton (1911–1985)
