Story: The Early History of the Airplane by Orville and Wilbur Wright


For two reasons we decided to use two propellers. In the first place we could, by the use of two propellers, secure a reaction against a greater quantity of air, and at the same time use a larger pitch angle than was possible with one propeller; and in the second place by having the propellers turn in opposite directions, the gyroscopic action of one would neutralize that of the other. The method we adopted of driving the propellers in opposite directions by means of chains is now too well known to need description here. We decided to place the motor to one side of the man, so that in case of a plunge headfirst, the motor could not fall upon him. In our gliding experiments we had had a number of experiences in which we had landed upon one wing, but the crushing of the wing had absorbed the shock, so that we were not uneasy about the motor in case of a landing of that kind. To provide against the machine rolling over forward in landing, we designed skids like sled runners, extending out in front of the main surfaces. Otherwise the general construction and operation of the machine was to be similar to that of the 1902 glider.
In order to show the general reader the way in which the machine operates, let us fancy ourselves ready for the start. The machine is placed upon a single-rail track facing the wind, and is securely fastened with a cable. The engine is put in motion, and the propellers in the rear whir. You take your seat at the center of the machine beside the operator. He slips the cable, and you shoot forward. An assistant who has been holding the machine in balance on the rail starts forward with you, but before you have gone 50 feet the speed is too great for him, and he lets go.
Before reaching the end of the track the operator moves the front rudder, and the machine lifts from the rail like a kite supported by the pressure of the air underneath it. The ground under you is first a perfect blur, but as you rise the objects become clearer. At a height of 100 feet you feel hardly any motion at all, except for the wind which strikes your face. If you did not take the precaution to fasten your hat before starting, you have probably lost it by this time. The operator moves a lever: the right wing rises, and the machine swings about to the left. You make a very short turn, yet you do not feel the sensation of being thrown from your seat, so often experienced in automobile and railway travel. You find yourself facing toward the point from which you started. The objects on the ground now seem to be moving at much higher speed, though you perceive no change in the pressure of the wind on your face. You know then that you are traveling with the wind. When you near the starting-point the operator stops the motor while still high in the air. The machine coasts down at an oblique angle to the ground, and after sliding 50 or 100 feet, comes to rest. Although the machine often lands when traveling at a speed of a mile a minute, you feel no shock whatever, and cannot, in fact, tell the exact moment at which it first touched the ground. The motor close beside you kept up an almost deafening roar during the whole flight, yet in your excitement you did not notice it till it stopped!

Answer 1

1. Air movement affects flight: "the wind which strikes your face"

2. The plane requires two people for flight: "An assistant who has been holding the machine"

3. The plane ride is remarkably smooth: "you do not feel the sensation of being thrown from your seat"

4. Speed is difficult to detect in the air: "you feel hardly any motion at all"

The given passage from "The Early History of the Airplane" provides evidence for each of the statements about the passage as follows:

1. Air movement affects flight:

- Label: "the wind which strikes your face"

- Evidence: The passage mentions that when flying at a height of 100 feet, the wind is the only noticeable sensation, indicating the impact of air movement on flight.

2. The plane requires two people for flight:

- Label: "An assistant who has been holding the machine"

- Evidence: The passage states that an assistant is present to hold the machine in balance on the rail during the start of the flight.

3. The plane ride is remarkably smooth:

- Label: "you do not feel the sensation of being thrown from your seat"

- Evidence: The passage describes that when making a turn, there is no sensation of being thrown from the seat, suggesting a smooth ride unlike experiences in automobiles or trains.

4. Speed is difficult to detect in the air:

- Label: "you feel hardly any motion at all"

- Evidence: The passage mentions that when flying at a height of 100 feet, there is hardly any perceived motion, except for the wind striking the face, implying that speed is difficult to detect while in the air.
