Wow! A Jet That Runs On Biofuel

I heard of a biofuel car many times, but was really surprised when I saw this post about a biofuel jet which made a successful test flight, on Washingtonpost .
This Experiment was carried by Virgin Atlantic ( Sir Richard Branson's airline) in collaboration with their partner Boeing on a Boeing 747 jet which flew from London's Heathrow airport to Amsterdam's Schiphol airport. This flight was partially fueled with a biofuel mixture of coconut and babassu oil in one of its four main fuel tanks. The jet carried pilots and several technicians, but no passengers.

Although the effectiveness of the biofuels in the battle against global warming is debatable , its a good experiment considering the growing oil prices.
