As the son of Igor Sikorsky, the inventor of the practical helicopter, Sergei Sikorsky has lived and breathed helicopters. From his father's 1939 VS-300 test flights to his own international career at Sikorsky Aircraft, Sergei Sikorsky watched the helicopter become an indispensable aerial tool for multiple civilian and military applications. Igor Sikorsky's vision of the life-saving helicopter was accurate; however, for every prediction that did not come true, totally-unexpected uses and missions suddenly appeared out of nowhere. As the great Yogi Berra once said, "predictions are very tricky, especially about the future." The GE Aviation Lecture Series is made possible by the generous support of GE Aviation.
