I have read the history and the feature about aeroplane.Here that I get:
History OF AEROPLANE
There have been many pioneers in the history of aeroplanes but the first to successfully fly an aeroplane were the Wright Brothers, Orville and Wilbur. Orville and Wilbur were skilled craftsmen and keen experimenters. They owned a business making and repairing bicycles. They were able to bring the value of a scientific approach to the invention of a heavier-than-air machine.
On the 17th of December 1903 they were successful in producing the world's first powered flight. Wilbur ran alongside the plane, Flyer, as Orville took off on the sand dunes outside a town called Kitty Hawk in North Carolina, USA. The flight lasted just 12 seconds and travelled 37 metres. This distance is less than the wingspan of a modern airliner, but it was a major accomplishment at the time.
The brothers received very little recognition in their home country. People were very sceptical about their achievement. On the 8th of October 1908, Wilbur flew their famous plane, Flyer, in front of a large crowd in France. The next day it was all over the French newspapers.

Why Do Aeroplanes Fly?
Aeroplanes planes are able to fly due to differences in air pressure. When a plane is on the ground, not moving, the pressure around it is the same top and bottom. The downward pressure of gravity is the same as the upward pressure of the ground. The plane has no lift.
A plane on the ground.
The shape of the wing gives the aeroplane the ability to lift of the ground. The wings are more curved on top than they are the bottom. As the wings move through the air, the air that travels over the top of the wings has further to move than the air travelling below. Air that moves faster has lower air pressure than air that moves slower. This means that there is lower air pressure above the wing than below. The result is an upward force or pressure and the plane is able to lift.

A plane is able to move forward because of the engine powered propellor. As it starts to move forward, the air pressure on the plane starts to change as the air moves over the wings. The upward pressure is now greater than the downward pressure of gravity and the plane starts to lift of the ground and is able to fly.

Synopsis of Robinson Crusoe
Captain of the Guinea Trading Ship
Arriving in London, Crusoe happens to meet the master of a ship bound for Guinea. The two men become friends, and Crusoe decides to make the journey too. Unfortunately, the man dies en route to Guinea.
Robinson Crusoe
The protagonist of Defoe's fictional autobiography, Crusoe is an adventurous man who rejects the expectations of his family and the constraints of the English middle class for a life on the high seas. After a devastating wreck at sea — of which he is the only survivor — he is forced to live confront his fear about being alone in order to survive the harsh demands of his lonely and solitary existence.Crusoe is not by nature a brave man. In time, his reason grows sharper and he conquers his fears. In fact, for a time he wanders the island without any weaponry. He learns how to do many diverse tasks, such as making an ax, baking bread, and building an elaborate shelter. When faced with marauding cannibals, he attacks them and rescues their captives. Finally, when he returns to London, he is able to readjust to English life and even gets married and has a family.
Friday
Friday is a native rescued by Crusoe; the young man eventually becomes his loyal servant. He is described by Crusoe as a Creole — a mix of African and Indian — and represents the wildness of nature. Through his relationship with Friday, Crusoe is able to confront his fear of the native people of the region.When Friday offers to exchange ideas with Crusoe on religion or technology, Crusoe refuses to learn from his knowledge. For example, when they begin to build a boat together, Friday wants to show Crusoe how to burn out the inside. Crusoe, however, insists on the more laborious method of using a hatchet. Crusoe's reluctance to treat Friday as an equal symbolizes general European attitudes toward "the savage."
Eventually, Friday becomes Europeanized, accepting English customs and religious concepts. He symbolizes the process of colonialization.
Old Savage
The Old Savage is one of the captives rescued by Crusoe and Friday; surprisingly, he turns out to be Friday's father. He too pledges allegiance to Crusoe.Portuguese Captain
The Portuguese Captain's ship rescues Crusoe from Africa, takes him to Brazil, and purchases Xury. He also helps invest Crusoe's money and acts as a father figure for him. He is an honest pilot of his crew and vessel and he serves Crusoe faithfully.The Spaniard
The Spaniard is one of the captives rescued by Crusoe and Friday. After they release and give him a weapon, the group is able to kill many of the cannibals. The Spaniard turns out to be an honest fellow who advises Crusoe to expand the plantation. The Spaniard's belief in Roman Catholicism is of no importance to Crusoe; what matters to him is that the Spaniard has a good work ethic and a true sense of honor.Xury
Xury is a servant that is forced into slavery with Crusoe. Fortunately, they are able to escape their masters. Xury, like Friday, naturally assumes the role of obedient and affectionate slave. Xury represents a European's notion of the non-European. He has better natural instincts — he is a natural hunter, a hide processor, he can see better at night (or day, for it is Xury who spots the Portuguese ship), and his sense of self-preservation is keener. Xury agrees to being sold into slavery on the condition that if he converts to Christianity he will be free in ten years.Synopsis
Robinson Crusoe is the name of a young Englishman who is shipwrecked on a deserted Island. He survivor himself. There is no chance of him being rescued so he has to start a new life. He manages to make his own clothes from animal’s skin, hunt for food, and make pottery. He also makes his own boat and shelter. To survive himself, he rears goats, plant rice and corn also collects some fruits.
One day, a native become his moist trusted companion and friend after he saves the native from a cannibal attack. He called the native Friday because he rescued him on Friday. Friday’s father and a Spaniard have been caught by the savage so Crusoe and Friday must rescue them. They also rescued an English captain from munity on his shop in another accidently rescue expedition. The captain offers to take Crusoe back to England. He accepts the offer and after 28 years of being away, he goes back to England.
