It has been shown how aeroplanes were built and made to fly, and not machines of one particular make, but biplanes and monoplanes of various types of construction; also how, granted he had a reliable motor, a man might fly for hours without alighting. These were the lessons of 1909; these, and the fact that flying was proved an art that could be learned by any man who was active and had sound nerves. After Wilbur Wright had taught his first pupils, and Bleriot and Farman had established training schools, men in rapidly increasing numbers came to learn to fly; so that, quite early in 1910, it was possible to list the names of more than 200 pilots. Progress was now revealed in two directions: firstly, encouraged by engine reliability, airmen made cross-country flights; and secondly, becoming more used to being in the air, and gaining confidence in the handling of their machines, they began to fly in gusty winds. This was shown by the fact that, fearing any breeze at first that was higher than 10 or 15 miles an hour, pilots soon combated winds of 20 and 25 miles an hour. Flights of 100 miles were made across country; one historic example, of course, was M. Paulhan’s 183-mile journey from London to Manchester, made in 242 minutes and with but one halt, by which he won _The Daily Mail_ £10,000 prize, and in which--meeting him in keen but friendly rivalry as the representative of England--he had the joint author of this book, Mr. Claude Grahame-White. The confidence of pilots in the reliability of their machines was demonstrated conclusively by the Comte de Lambert. Rising from the aerodrome at Juvisy, near Paris, he flew over the city and circled the Eiffel Tower, returning afterwards without accident to his starting-point. Several more airmen had, by this time, succeeded in crossing the Channel, and a notable feat was that of the Hon. C. S. Rolls, who flew from Dover till he reached the French coast near Calais; then, circling without a descent, he returned to his starting-point--a flight over-sea that lasted an hour and a half. In high flying, too, the confidence of airmen was displayed. At Rheims in 1909, it may be remembered, Latham rose 500 feet, and this was considered remarkable. But the record, during 1910, was beaten and beaten again, until it stood at nearly 10,000 feet. In speed also, using monoplanes with 50-h.p. motors, pilots made records day by day; and an English airman, Mr. Radley, flying over a measured course in August 1910, in a Bleriot monoplane, attained a speed of more than 70 miles an hour.
