Today we"ll take about pilot Wiley Post. He set new records when he flew his own airplane around the world in 1933.
Nothing in Wiley Post"s early years suggests that he would become a famous pilot. He was born in 1898. His family were farmers. In 1913, Wiley saw something that forever changed his life—an airplane. Wiley Post began to study everything he could find about flying. His self-education would continue for the rest of his life. Post finally rode in an airplane in 1919. At the time, many people believed all pilots were special people. They believed it took special skills and courage to fly an airplane. But after his first ride, Wiley Post knew that flying was something he could learn to do.
Wiley Post began his career in flying, not as a pilot, but as a performer who jumps from airplanes using a parachute. Wiley Post then decided the only way to become a good pilot was to buy an airplane of his own. He needed more money than he earned in the flying show. He went to work in the oil-producing areas of Texas. But he damaged his left eye in an accident. At first, Post thought his days as a pilot were ended. A pilot needs to be able to judge distance. Wiley Post began teaching himself to judge distance with only one eye. He worked hard at training his eye and brain to tell the correct distance. It took a long time, but he succeeded.
