The Wright Brothers
Wilbur Wright was born to Milton and Susan Wright on April 16, 1867 in Millville, Indiana. Orville was born in Ohio on August 19, 1871. Both were born to Milton and Susan Wright. They had two brothers name Lorin and Reuchlin, and a younger sister, Katherine. Their parents raised them to be self-confident and to always pursue their dreams.
The Wright brothers's father, Milton Wright's preaching caused him to be on the road preaching, but when he comes home he brings back small toys for his children. In 1878 he brought back a small model helicopter for his boys. Made of cork, bamboo and paper, and powered by a rubber band to twirl its blades, the model was based on a design by the French aeronautical pioneer Alphonse Pénaud.
The Wrights brother never got married and continued to live in the family home. Wilbur died on May 30, 1912 at the age of 45 from typhoid fever. Orville died on January 30, 1948 at the age of 76.

Negative and Positive Effects
Before the first airplane was invented by the Wright Brothers, inventors made numerous attempts to make items fly like the birds. These early inventions included kites, hot air balloons, airships, gliders, and other devices.
On December 17, 1903, the Wright brothers made the first successful experiment in which a machine (aka airplane) carrying a man rose by its own power, flew naturally and at even speed, and descended without damage.
On November 21 1783, the first hot air balloon was lifted at a height of two hundred and seventy feet, they waved their hats and saluted the applauding spectators. Then the wind carried them away toward Paris.
Timeline

Continued
While air balloons allowed mankind to float, inventors dreamed of making flying machines that would allow mankind to have controlled flight.
the first patent on a flying machine was recorded in 1709 when Bartholomeo de Gusmao, appeared before the King of Portugal to announce that he had invented a flying machine. But the inquisition happened and Bartholomeo de Gusmao was pronounced as a person who claims or is believed to have magic powers, his flying machine was destroyed, and he was imprisoned until his death.
In 1796, George Cayley made an instrument of whalebone, corks, and feathers, which by the action of two screws of quill feathers, rotating in opposite directions, would rise to the ceiling.
1891 Otto Lilienthal made the first glidder
1894 Octave Chanute published "Progress in Flying Machines" The Wright Brothers used this book as a basis for much of their experiments
1903 The Wright Brothers - First Flight
Orville Wright and Wilbur Wright were very deliberate in their quest for flight. First, they spent many years learning about all the early developments of flight. They completed detailed research of what other early inventors had done.

Positives:
1. Easy way to get transported from place to place.
2. Brings people all over the word closer together
3. Make evacuation an easier, when their is a problem.
4. Easy way to cross over long bodies of waters.
Negatives:
1. It releases pollution into the air.
2. It is one of the reason why we have global warming today.
3. Most crew drivers have a sighn of hearing lost, cardiovascular problems, and problem with their vision
