Fifty-three years ago today, on October 26, 1972 (September 20, 1972 in the lunar calendar), Sikorsky, the inventor of helicopters, died. On October 26, 1972, Sikorski died at his home in Easton, Connecticut, at the age of 83. He was an aviation pioneer who invented the first practical helicopter. Sikorski's other aviation inventions included compound engine aircraft and spacecraft, but he said that the most important event in his life was his successful pilot of the "VS300" helicopter designed and built himself on September 14, 1939. Sikorsky Aircraft Manufacturing Company, which he founded, has manufactured 5,000 helicopters so far. As a child, Sikorsky dreamed of building a helicopter after reading Jules Verne's science fiction novels in Russia. After the Russian Revolution, he went to France and later to the United States, by which time he was already an effective aircraft designer. He believes that helicopters should replace cars and be widely used in people's daily life. People should fly in helicopters around the city, stand on the roof of buildings, and then go to work. Sikorski's first achievement in the United States was the 4-engine "S40" airship, which was used by Pan Am Airways; Later, Sikorski Company, which has become a subsidiary of United Airlines, concentrated on producing helicopters.
