The development of helicopters is chronicled from Da Vinci’s drawings, through Cierva and Pitcairn’s autogyros, to Sikorsky, Bell, and others whose post war helicopters vied for the civilian market.
As a crop duster during an agricultural crisis, and in the Korean War, the helicopter proved to be a practical flying machine.
