The ban on monoplanes, it may be remarked in passing, was a heavy blow to one of the earliest pioneers of aviation in this country. Mr. L. Howard Flanders, who had worked with Mr. A. V. Roe at Lea Marshes, and had designed the 'Pup' monoplane for Mr. J. V. Neale at Brooklands, had subsequently formed a company for the building of aeroplanes, with works at Richmond. He obtained a War Office contract for four monoplanes, but when, after trial, he was engaged in reconstructing the under-carriages, the use of the monoplane was forbidden to army pilots. This and other disappointments put an end to Mr. Flanders's building activities, but his name deserves record among the pioneers. When Lieutenant B. H. Barrington-Kennett of the Grenadier Guards became adjutant of the Military Wing of the Royal Flying Corps he made a vow that the corps should combine the smartness of the Guards with the efficiency of the Sappers. In spite of difficulties and disasters, the corps went far, in the first two years of its existence, towards attaining that ideal. In the summer of 1912 the Central Flying School at Upavon got to work, and thenceforward supplied a steady stream of trained reinforcements for the corps. There was inevitable delay at first; but as soon as some of the new wooden buildings were nearing completion they were taken over, and on the 19th of June the school was opened. The plan was that there should be three courses every year, each of them lasting three months and passing on its graduates for further training either with the military squadrons or at the naval school. The first course began on the 17th of August 1912, and was not completed until the end of December, but the subsequent courses were punctually completed in the time prescribed. The delay in the first course was due chiefly to a shortage of machines. The use of monoplanes was forbidden, and the nineteen pupils who presented themselves in August had to be instructed on the only four available biplanes, which were soon damaged by the maiden efforts of the learners. For a short time the pupils were sent on leave, and the school was closed; then new machines and new recruits began to arrive, and the work of education went forward. Besides the main business of flying, the pupils were instructed and examined in map-reading and signalling, the management of the internal-combustion engine, and the theoretical aspects of the art of reconnaissance. Of a total of thirty-four pupils who were examined at the end of the course, only two failed to pass. During the next year and a half, up to the very eve of the war, the work of the school went on steadily, with improving material and increasing efficiency. There were three fatal accidents: on the 3rd of October 1913 Major G. C. Merrick was killed on a Short biplane; on the 10th of March 1914 Captain C. P. Downer, on a B.E. biplane; and on the 19th of March 1914 Lieutenant H. F. Treeby, on a Maurice Farman biplane. On an average about thirty
