Mad Max like Gyrodyne Rotorcycle is on display for your up close perusal at the National Museum of Transportation in our Really Cool Stuff exhibit. This small-sized helicopter was dropped to downed pilots stranded behind enemy lines by the U.S. Navy. This particular model is equipped with Porsche 4-cylinder internal combustion engine. Our rotorcycle is just one of several unique pieces in our Orthwein’s visitor center, some never on display before now!
