Bristol 171 Sycamore

The Bristol 171 Sycamore in Hangar-8 is the only existing example of its type in the world that is still capable of flying. The Sycamore takes its name from the English tree known as the sycamore maple. Why? Anyone who has seen the slow revolving motion of a sycamore seed as it falls from the tree will understand precisely why. Added to this, the rotor blades are made of Australian maple wood and initially this was a source of major concern.
