We shall see hundreds of thousands of privately owned direct-lift machines carrying Americans about their business and their pleasures.
Igor was a technical visionary, but I believe he fell short in some of the business vision. Part of his early business vision was that flying boats would always be more viable that landplanes that needed runways, and that many smaller aircraft would be more practical than lesser large ones. On the bright side, when the flying boat market failed, he got to get back to his dream of perfecting the helicopter. Interesting that although his technical vision started with coaxials, it matured into the conventional single main rotor and tail rotor.
