Thanks! Aviation documentary video by AeroSpaceNews.com Back in 1989 when this award winning story was produced, everyone was talking about Ultra High Bypass (UHB) jet engines. The topic of airline CO2 emissions and those greenhouse gases associated with air travel were subject of an ICAO deal on 6 October 2016. Please leave a comment or ask a question! FYI: This video was uploaded in 2009 - WE KNOW the opening/ending are too long. Check out our more recent videos - we got the memo! Download the thumbnail picture: http://goo.gl/YEolkE General Electric (GE) was testing the Unducted Fan (UDF) and a team of Pratt & Whitney and Allison were experimenting with a geared PropFan design. Test platforms consisted of a Boeing B-727 and a then Douglas MD-80 with most flights taking place at California's Mojave Airport. This video also includes an appearance by the late brilliant Aviation Week Editor Michael Dornheim. He will be missed. Clearly, this video is from our archive, not a recent production.
