ets usually run on high-octane oil byproducts, however, NASA has tested jets running on fuel based animal fat. In March and April of this year, researchers at the NASA Dryden Flight Research Center in California tested biofuel made of chicken and beef waste fat in the engine of a DC-8 airplane. NASA hopes that the study makes people realize that biofuels do not necessarily have to come from plant sources. According to NASA, fuel can come from algae or rendered animal fat. NASA doesn’t believe that fossil fuels are necessary as a fuel source.
The researchers tested the new animal-based biofuel through an engine burning Jet Propellant 8 fuel, similar to the industry standard Jet-A used in commercial aircraft.
