Windecker E-5
From Wikipedia, the free encyclopedia
The Windecker YE-5A was an experimental aircraft evalutated by the U.S. Air Force. It was an all-composite construction aircraft, based on the commercial Windecker Eagle. The YE-5A, delivered in 1973, was used in tests relating to the radar detectability (commonly known as 'Stealth') of composite aircraft. The composite airframe was shown to be difficult to detect using radar; however, other components, including the metal engine, could be seen on radar. The aircraft was then transferred to the U.S. Army for use in further tests. A single YE-5A (serial number 73-1653) was built. It is preserved in the U.S. Army Aviation Museum at Fort Rucker, Alabama.
