Helicopters are so much a part of life that we tend to forget, or more likely never knew, that they have a natural tendency to crash, unlike a fixed wing aircraft that still has some lift after loss of power. And the cyclical loads on the rotor hub are tremendous. Still, many lives are saved ever year because helicopter are close by for transport. We have one at our local airport about three blocks from us and it flies often. Headed for Omaha or Lincoln. And sometimes Sioux City,Iowa.
