It was an all-composite construction aircraft, based on the commercial single-engine, low-wing 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. This aircraft was destroyed in a crash during flight testing, and was replaced by a conventional civilian model Windecker Eagle. This aircraft is disassembled and in storage in the United States Army Aviation Museum at Fort Rucker, Alabama. Eagle Behind the Curtain. Accessed 2010-06-10.
