Aviation is the flying or operating of an aircraft. People who fly aircrafts are called aviators. Over the years there have been many talented aviators. Percy Pilcher, an English engineer and aviation pioneer, was one of them.
In the 1890s, Pilcher built and flew a glider, a light aircraft that flies without an engine, called the Hawk. However, his dream was to achieve powered flight. He wanted to soar like the birds flying fast and high in the air! He built another soaring machine, this time, with an engine.
In 1899, he was ready to make his first test flight with his powered soaring machine. Unfortunately, the engine broke. Not wanting to disappoint the audience, he decided to fly the Hawk instead. Sadly, he crashed and died.
In 1903, two American brothers, called the Wright brothers, achieved the first powered flight. One hundred years later, in 2003, at the time of the centenary of powered flight, a replica of Pilcher’s plane was built and flown. This exact copy of Pilcher’s plane achieved a controlled flight of one minute and 26 seconds, longer than the Wright brothers’ first flight of 59 seconds.
