"A second-generation biofuel will be blended with jet fuel and tested in one of the four engines of a JAL Boeing 747-300 aircraft equipped with Pratt & Whitney JT9D engines. The biofuel to be used has not been decided yet. JAL will provide the aircraft and staff for the short approximately 1 hour demonstration flight out of an airport in Japan scheduled for the end of FY2008, the year ending March 31, 2009. The flight will be the first biofuel demonstration by an Asian carrier, and the first using Pratt & Whitney engines."

Hopefully they can do a better job than VS on the demonstration.
