Voice one:

The final design had one main rotator, or rotor. The rotor was connected to three long blades on top. These blades turned around like an album on a record player. They lifted the helicopter into the air. A smaller rotor, with shorter blades, was at the back end. Those blades turned around like the wheel of a car. They kept the body of the helicopter pointed forward.

This remained the basic design of all Sikorsky helicopters.

Voice two:

By nineteen forty-one, the V-S-Three-Hundred had set all world records for helicopter flight. Military versions were made and some were used in the last years of World War Two. Most people, however, still did not accept the new flying machine. They said the helicopter had to prove its worth. It did that during the war in Korea in the early nineteen fifties.

Helicopters take off straight into the air. They can land just about anywhere. They do not need long airport runways like planes. During the Korean War, helicopters flew into battle areas to rescue wounded soldiers. They flew the men quickly to medical centers set up away from the fighting. This greatly improved the men's chances of survival.

Voice one:

Igor Sikorsky, the man most responsible for successfully designing and building helicopters, thought helicopters would be a common form of transportation. People, he said, would use them instead of automobiles. They would fly into a city, land on top of a building, go to work, then fly home again.

This has not happened. Privately-owned helicopters are not common. Yet helicopters have proved their value in other ways.

Companies use them to transport heavy equipment to hard-to-reach places. Farmers use them to put insect poisons on their crops. And emergency teams use them to rescue people from fires and floods.

Voice two:

Igor Sikorsky continued as an engineering adviser to his aircraft company until he died in Nineteen-Seventy-Two. He was one of the best-known and most respected leaders in international aviation.

He received more than ninety major awards and honors from many countries and organizations.

He always said, however, that his greatest satisfaction did not come from receiving honors. It did not come from being the first person to design new kinds of aircraft. Igor Sikorsky said his greatest satisfaction came from knowing that his helicopters were responsible for saving lives.
