СКАЧАТЬ how does one know when to do it?"

      "That comes with practice-and the feel of the ship. As flying speed is gained, I give a momentary pressure on the elevators (like this) – and break the hull out of the water-so-easing the pressure immediately after the instant of take off. Now that we are in the air our speed is only slightly above minimum flying speed. Any decrease in this would result in a stall. That is why I keep the nose level for six or seven seconds in order to attain a safe margin above stalling point before beginning to climb."

      "There's certainly a lot more to it than I ever dreamed!"

      "You bet there is. I haven't told you the half of it yet. One thing I forgot to say-you must always hold a straight course while taxiing before the take off. Also, never allow a wing to drop while your plane is on the step. – We've got enough speed on now, so I'll pull back the stick and let the plane climb for a bit."

      "But you're heading for the Long Island Shore directly away from New Canaan-" she protested, "why don't you bring her about-not that I'm in any hurry, but-"

      "This is an airplane, not a sailboat, Dorothy. All turns must be made with a level nose. If I should try to turn while in a climb like this, a stall would probably result, and with the wing down the plane would most likely go into a spin and-"

      "We'd crash!"

      "Surest thing you know!"

      "Oh!"

      "But the altimeter on the dash says one thousand feet now. We're high enough for our purpose. So I push the stick forward, like this-until the nose is level-so! Now, as I want to make a right turn, I apply right aileron and simultaneously increase right rudder considerably."

      Dorothy saw one wing go up and the other go down. She was hardly able to keep her feet as the plane's nose swung round toward the Connecticut shore.

      "Isn't that called banking?"

      "Right on the first count," replied Bill.

      "Why do you do it?"

      "Because in making a turn, the momentum of the plane sets up a centrifugal force, acting horizontally outward. To counteract this, the force of lift must be inclined until it has a horizontal component equal to the centrifugal force. The machine is therefore tilted to one side, or banked, thus maintaining a state of equilibrium in which it will turn steadily. No turn can be made by the use of the rudder alone. The plane must be banked with ailerons before the rudder will have any turning effect. – Get me?"

      "I get the last part. Guess I'll have to do some studying."

      "Everybody has to do that. But I'll lend you some books, so you can bone up on the theory of flight. What I said just now amounts to this: if you don't bank enough you send your plane into a skid."

      "Just like an automobile skids?"

      "Yes. But of course the danger doesn't lie in hitting anything as in a car. A skidding plane loses her flying speed forward and drops into a spin. On the other hand, if you bank her too sharply, you go into a sideslip!"

      "And the result in both cases is a crash?"

      "Generally. But I think you've had enough instruction for today."

      "Oh-but I want to know how you ended that turn. We're flying straight again now-and I was so interested in what you were saying, I forgot to watch what you did!"

      "Well, after I had banked her sufficiently, I checked the wings with the ailerons and at the same time eased the pressure on the rudder. Then I maintained a constant bank and a constant pressure on the rudder pedal throughout the turn. To resume straight flight, I simply applied left aileron and left rudder: and when the wings were level again, I neutralized the ailerons and applied a normal amount of right rudder."

      "My goodness!" exclaimed Dorothy-"and that is only one of the things I have to learn. I thought that flying a plane wouldn't be much more complicated than driving a car."

      "Oh, it's simple enough-only you have to balance a plane, as well as drive it."

      "Do you think I'll ever learn?"

      "Of course you will. It takes time and practice-that's all."

      "I wonder how birds learn to fly?" Dorothy glanced down at the wide vista of rolling country over which they were traveling. The dark green of the wooded hills, the lighter green of fields, criss-crossed by winding roads and dotted with houses, all in miniature, seemed like viewing a toy world. And here and there, just below them, there was the occasional flash of feathered wings, as the birds darted in and out among the treetops.

      "Birds have to learn to fly, too. They get into trouble sometimes."

      "They do?"

      "Certainly-watch gulls on a windy day-you'll see them sideslip-go into spins-and have a generally hard time of it!"

      "Oh, really? I'd never thought of that. But of course they can fly much better than a plane."

      Bill shook his head. "That's where you are wrong. No bird can loop, or fly upside down. Reverse control flying and acrobatics-stunting generally is impossible for them. – But look below! Recognize the scenery?"

      "Why, we're almost over New Canaan. There are the white spires of the Episcopal and Congregational churches-and there's Main Street-and the railroad station!"

      "And over on that ridge is your house-and mine across the way," he added. "Well, here's where I nose her over. Hold tight-we're going down."

      TROUBLE

      After releasing the rectractible wheel landing gear, which turned the big amphibian from a seaplane into one which could land on terra firma, Bill brought his big bus gently down to the ten acre lot behind the Bolton residence.

      As the plane rolled forward on its rubber tired wheels and came to a stop, two men came walking in its direction from the trees at the edge of the field.

      "Here come our respective fathers-" announced Bill, stripping off his headgear. "Remember-I take all responsibility for bringing you back in the plane."

      "You-do nothing of the kind!" Dorothy's tone was final. She handed him her head-phone and running back through the cabin, vaulted the low bulwark to the ground.

      Bill hurriedly made things secure in the cockpit and followed her.

      "And so you see, Dad," he heard her say, as he approached where they stood, "Bill not only saved my life-he took all kinds of chances with his own, flying in a gale like that. And-oh! I forgot to tell you that he warned me not to go out in the Scud this afternoon!" she ended with a mischievous look toward Bill.

      Mr. Dixon was a tall man, whose tanned, rugged features and searching gaze suggested the sportsman. He turned from his excited daughter, with a smile and an outstretched hand.

      "I'm beginning to realize, young man, that I owe you an apology for my shortness over the phone. Judging from Dorothy's story, I can never hope to express my gratitude for what you've done today."

      Bill mumbled an embarrassed platitude as he shook hands, and was glad when Mr. Bolton broke into the conversation.

      "The Boltons, father and son, were probably born to be hung," he chuckled. "It's СКАЧАТЬ
