The inventor of the helicopter's son gave a speech at Utah Valley State College on Wednesday, where he discussed the invention of the helicopter. An article about the speech is located here, and in part, the article states:
Throughout it all, he explained the role his father played.
"There's a secret to this that the birds have been trying to teach us for a million years," he quoted his father concerning the invention of helicopters. "It is far more intelligent to stop and then land than it is to land and then try to stop."
Sikorsky's father was a Russian-born scientist who started the idea of the helicopter as a student in Paris. After building his first two models in 1909, and failing to get either one off the ground, Igor Sikorsky turned his attention to fixed-wing aircraft.
*****It wasn't until 1939, 30 years after his first attempt, Igor Sikorsky made the worlds' first successful helicopter.
"Anything, anything that one man can imagine, other men will later make true," Sikorsky said, quoting his father.
