The Air Force flew an F-15 for the first time on a fuel blend containing a biomass-derived fuel and standard JP-8 aviation fuel at Eglin AFB, Fla., Oct. 22, 2010. The biomass-derived portion of the fuel blend is known as hydro-treated renewable jet fuel, or HRJ. It is one type of alternative aviation fuels that the Air Force leadership wants to certify the entire aircraft fleet to run on as a means of reducing dependence on foreign sources of energy. The F-15 is the second USAF platform, following the A-10, to run on this fuel. Animal fat and plant oils are the feedstock for HRJ. Here, SSgt. Matthew Bardell (l) and SrA. Jacob Prine connect a fueling hose to the F-15 prior to the flight test.
