During the last war the term CAVU was born. The first letter of each word in the phrase Ceiling and Visibility Unlimited is used, forming the combination CAVU. The first time one hears it, he finds nothing unusual in the word; but if memory is given its freedom, he recalls a multitude of happenings from the last war, with the anguish and heartbreaks accompanying these events; and then suddenly the significance of CAVU flashes across the sky of one's imagination. Out of the darkness, discouragement, and despair, there comes the promise of unlimited visibility and a ceiling without limitation. When one is in the thick of the storm, the flash which brings the word is most welcome. There is more than the dramatic in such an experience; there is a renewal of purpose and unexpressed gratitude for another chance. As the aviator assigns an important place to the term CAVU, so all of us who walk the earth in pursuit of the ordinary, not the spectacular, need also to recognize the significance of the term. Each year colleges and universities all over the world graduate thousands of young men and young women who are equipped with tools with which they are supposed to do at least three things: -first, cut out, construct, reconstruct, and thereby create a better world; second, earn the equivalent of a decent and adequate living; and, third, discover the secrets and repossess the knowns of life in such a manner as to find beauty, truth, and righteousness. This is a large assignment, and many there are who start out bravely and enthusiastically, but who fall by the wayside when the conditions of travel become extremely difficult and frequently almost intolerable. To these CAVU gives new hope and new life, for the knowledge that the present darkness will soon give way to light helps to strengthen stumbling and faltering feet. In developing visibility unlimited, I propose four points, all of them fitting properly into our phrase. First: And, or life's dimension of height. The ands of life are the altimeters which measure the height to which we climb. It seems peculiar that we must forever remind ourselves that our progress is a composite of ands. As the aviator climbs to amazing heights because of a series of ands, so we rise in life, not alone but with and by the help of others.
