per or at his command the way these mechanical birds sail along through the sky looks surprisingly simple but is it so easy sure there's nothing to it take the wheel for example you can make the ship do most anything by moving it like this you can turn it over to luke dies and fly upside down say it is all you have to do there's nothing to force you have to watch where you're going all the time keep your eyes on these instruments they're all there's one thing this expert forgot that is he knows cowl and in what he know is his safety a fellow learns to fly with the army air corps he doesn't learn it all in the day a week or even a month the gateway to the air service is a big schooling ground at san antonio texas the primary training point for army pilots physical tests come first before you can even be considered every applicant proves himself sounded every way if the student reacts properly with twenty seconds to live he is ready for the next  ability to judge distance and timing is determined from the result of a depth perception test the student adjusts the controls to bring the two uprights an equal distance from his eyes he gets a thorough test on the coordinator to find out how quickly he will react later in the air every army pilot must be an expert radio operator to be able to understand signals in the a is knowledge of what you are depending on before the aerial now is never leave the grown he knows all open wires on the powers of his engine are trained here it helps a lot in knowing the condition of the engine in the air and that makes for safety too in the classroom this student learns why an airplane can fly the lines on this chart represent the pull of when the number of lines represent the amount of air le on the upper services than on the lower causes the plane to be lifted upward a small scale model helps teach the theory of flight the link trainer explains how the controls are operated and what effect their movements have upon a play in the air in the link trainer preliminary instruction in instrument flying is given the student practice is straight and level flying normal turns climbing and gliding turns stones and spins and flying a course on the radio beam then comes the work on an actual plane the army pilot must know how to take the best possible care of his airplane the greatest care means the greatest safety later in the air one of the most important parts of the student's training is learning how the plane operates and how it responds to the controls the flyer must understand every part of an airplane's assembly from the propeller to the rather after many hours of preliminary training the student gets his first chance to fly on first flight the plane is always equipped with dual control and an instructor goes along to guide him at the end of the eight to eleven hours of flying with fuel controls the instructor can flight far away from the rest of the squad the student gets the feel of the sky with the greatest possible safety there is a perfect three point line into his credit couldn't be better he knows his playing and how to control it it's easy to drive an automobile to but here again the greatest back door in safety is our knowledge of what you are driving and how it can be controlled anybody can start a car whether we know anything  power and brakes or not it's easy to push down accelerators release clutch pedal it's easy to shift the silent synchromesh gears and it's easy to start the car with perfected hydraulic brakes but like the expert flyer the driver of a modern high powered motor car should know all we can learn about automobiles the beginner should have an understanding of his automobile before you ever attempt to drive in traffic every driver should know the traffic rules so well that he will automatically obey them and drive safely all the time every car has its instruction book the driver should study it and learn all he can about how his car works and how to take care of it he should have several hours of instruction at the controls and finally the first solo out where there is plenty of room for him to practice of course every driver cannot be expected to know quite as much about his car as every pilot knows about his plane but there are millions of safe drivers on our highways today the safe driver knows his brakes and he knows how to use them just stop without getting a safe driver knows his transmission and how to start on slippery roads without spinning the wheels the same driver knows the braking power of his
