The National Research Council of Canada has successfully conducted the world's first flight fully powered by drop-in biofuels. Prior to this, all biofuel test flights have used a combination of drop-in biofuels and jet fuel. Biofuels Digest reports:
Using Applied Research Associates’ proprietary catalytic hydrothermolysis process, oil from Resonance Energy Feedstock was converted into a fuel that represents a complete replacement for conventional jet fuel, enabling flight at 100% biofuel use, a breakthrough for the renewable fuels industry. This historic flight symbolizes a significant step for the aerospace industry.
