Helicopters took a lot of their early inspiration from one of nature’s most efficient fliers in the dragonfly, and host Danni Washington’s going to take one for a spin to see exactly how. She’ll also take a look at how this insect and the wings of owls continue to inspire helicopters. Part of the "Nature Knows Best" series.
