The idea of this little book is to give as clear and graphic a description of modern aviation as circumstances will permit; of the new, heroic race of men to which Flying has given birth; of the conditions under, and the elements in, which their work is carried out, and the difficulties and dangers they have to encounter. Flying is essentially a profession for the younger generation. The strain is too great for men of more mature years. To withstand such strain requires all the vigor, the recklessness, the iron nerve of youth. It is a profession that offers an irresistible appeal to healthy-minded, sport-loving youth, to whom adventure is the nectar of existence.
