Vertical Speed Indicator

Famous quotes containing the words vertical and/or speed:

    I tell you, hopeless grief is passionless;
    That only men incredulous of despair,
    Half-taught in anguish, through the midnight air
    Beat upward to God’s throne in loud access
    Of shrieking and reproach. Full desertness,
    In souls as countries, lieth silent-bare
    Under the blanching, vertical eye-glare
    Of the absolute Heavens.
    Elizabeth Barrett Browning (1806–1861)

    Among the laws controlling human societies there is one more precise and clearer, it seems to me, than all the others. If men are to remain civilized or to become civilized, the art of association must develop and improve among them at the same speed as equality of conditions spreads.
    Alexis de Tocqueville (1805–1859)
