In a test flight that carried no paying customers, Virgin Atlantic flew a Boeing 747 from London's Heathrow Airport to Amsterdam's Schiphol Airport, while one of its four engines used a mixture of coconut oil and babassu oil. The fears where that at altitude the biofuel might freeze and therefore only one engine was tested and apparently all worked well. Critics of the biofuel movement include Greenpeace and say that cultivating crops to make biofuel is not sustainable and will lead to reduced land for food production while those behind the technology are hoping that biofuel will have a lower carbon footprint than fossil fuels. "Some of us in the industry are actually doing something about reducing our carbon emissions. I don't think that's a gimmick. It's progress," said Paul Charles, Virgin Atlantic spokesman.
