After many preliminaries an appointment was secured at the War Office with a High Official of Military Aeronautics. There “Theta” was subjected to a curiously interesting catechism which seemed to touch on nearly every possible branch of activity under the sun except aviation. Finally the High Official, probably seeing a way of ridding himself of a candidate who had accomplished little or nothing of the various deeds of daring enumerated in the Shorter Catechism, suggested an immediate medical examination on the premises. That ordeal safely passed, “Theta” returned to his catechist, who said wearily, “Well, we’ll try you, but you know you have not many of the qualifications for a flying officer.” “Theta” returned to school to await his summons, which was promised within two months. The school term ended; a motor-cycling holiday in Devon followed--and still no call. On the return to London a reminder was sent to the War Office. There immediately came a telegram ordering “Theta” to report for instruction at what may be called Aerodrome “A.” Training began almost at once with a joy-ride of ten minutes’ duration. But the weather was for the most part what the aviators in their slang call “dud.” An “abominable mist” hung over the aerodrome, and consequently, though the period of instruction was fairly prolonged, the opportunities for flights were few. There was much waiting and little flying, and the bored youth was driven to music and rhyming to fill up the interstices. But before the end of the year a good deal had been accomplished. At the close of his eleventh lesson “Theta” was told to hold himself in readiness for a “solo” performance. After four more flights came the successful tests for the “Ticket” which transforms the pupil into a certificated aviator. This preliminary triumph was celebrated the same evening by a joy-ride at nearly 2,000 feet, the highest altitude that “Theta” had reached on a solo performance. Nearly four years and a half had elapsed between the schoolboy “Ticket” and the real thing. Then came a transfer to another and more advanced type of machine. On this there were but three flights with an instructor, and then another “solo” performance. Towards the close of the year “Theta” left Aerodrome “A” for Aerodrome “B,” having in the meantime been gazetted as a probationary second lieutenant, Special Reserve. The advanced course occupied about three months. It proved more exciting in many ways. In the elementary portion of training “Theta” saw many “crashes,” none of which, however, proved fatal. In the second, war conditions more nearly prevailed, and at times--when, for example, three colleagues lost their lives in flying, and a Canadian friend who shared his hut in training was reported “missing, believed killed,” within a few weeks of reaching the front--the stern realities of his new profession were driven home.
