Airport workers fuel up a plane at Shanghai Hongqiao International Airport early Wednesday morning before a test flight. Sinopec, China's top oil refiner, later announced the success of the first test flight powered by the company's newly developed aviation biofuel product. The China Eastern Airlines Airbus A320 had landed after completing a smooth 85-minute journey using the biofuel, the company said. The biofuel is made from palm oil and recycled cooking oil. -Dong Jun
