Answer:
Wilbur and Orville Wright were American inventors and pioneers of aviation. In 1903 the Wright brothers achieved the first powered, sustained and controlled airplane flight; they surpassed their own milestone two years later when they built and flew the first fully practical airplane.
Always working on different mechanical projects and keeping up with scientific research, the Wright brothers closely followed the research of German aviator Otto Lilienthal. When Lilienthal died in a glider crash, the brothers decided to start their own experiments with flight. Determined to develop their own successful design, Wilbur and Orville headed to Kitty Hawk, North Carolina, known for its strong winds.
Wilbur and Orville set to work trying to figure out how to design wings for flight. They observed that birds angled their wings for balance and control, and tried to emulate this, developing a concept called “wing warping.” When they added a moveable rudder, the Wright brothers found they had the magic formula-on December 17, 1903, they succeeded in flying the first free, controlled flight of a power-driven airplaine. Wilbur flew their plane for 59 seconds, over a distance of 852 feet, an extraordinary achievement for their time.
The Wright brothers soon found that their success was not appreciated by all. Many in the press, as well as fellow flight experts, were reluctant to believe the brothers’ claims at all. As a result, Wilbur set out for Europe in 1908, where he hoped he would have more success convincing the public and selling airplanes.

Answer:
The Crusades were Christian military movements towards the Holy Land in order to occupy and keep it under Christian rule.
- 11th century Europe was thriving. With the end of the barbarian invasions, a period of stability and an increase in trade began. Consequently, the population has also grown. In the feudal world, only the firstborn inherited the feuds, which resulted in many men for little land. The men, with no land to make a living, plunged into crime, stealing, looting and kidnapping. Something needed to be done.
- As stated earlier, the Christian world was divided. Because they disagreed with some dogmas of the Roman Church (worship of saints, demand for indulgences, etc.), Eastern Catholics founded the Orthodox Church. Jerusalem, the Holy Land, belonged to the Arab domain and until the 11th century they allowed Christian pilgrimages to the Holy Land. But at the end of the 11th century, peoples of Central Asia, the Seldjuk Turks, took Jerusalem. Converted to Islam, the Seldjúcidas were quite intolerant and prohibited the access of Christians to Jerusalem.
- In 1095, Pope Urban II called for expeditions to retake the Holy Land. The crusaders (as the dispatchers became known) received this name for carrying a large cross, the main symbol of Christianity, stamped on their clothing. In exchange for participation, they would gain the forgiveness of their sins.
- The Church was not the only one interested in the success of these expeditions: the feudal nobility was interested in the conquest of new lands; mercantilist cities like Venice and Genoa were dazzled by the possibility of expanding their business to the East and everyone was interested in oriental spices, due to their high value, such as: black pepper, cloves, nutmeg, cinnamon and others. Moved by faith and ambition, between the 11th and 13th centuries, eight Crusades left for the East.

The allies had two main differences with the germans, one of them was <em>they had to flew for a longer time and a longer way to reach battle field, </em>the other one is they had electric starters for their airplanes making it easier to start in every climate situation you may face.
The germans copied the big tank fuel, and the bigger cockpit, also the electrical starting switches, prior to this the germans had a hard time starting their engines in the cold russian weather.
