Virgin Atlantic became the first commercial airplane operator to fly a plane powered partially by palm oil this week. The jet's engine had not been given any special modifications and there had been some doubts about whether the palm oil would gum up when exposed to the low temperatures of the altitude, but all went well. The only remaining issues, according to the article, are the economic and ecological ramifications of using palm oil. It might drive up the prices of cooking oil in certain parts of the world, and people might cut down rainforests for palm plantations
