The ecoDemonstrator Program is a flight test research program of Boeing, which has used a series of specially modified aircraft to develop and test aviation technologies designed to improve fuel economy and reduce the noise and ecological footprint of airliners. Additional stickers (when compared to the picture above) were added during the tests in Spring 2018. All decals were removed when the aircraft was delivered to FedEx.
