Green Flight International flew the World's first jet aircraft on 100% biofuel. The flight from Nevada's Reno - Stead airport was in a single engine L-29 piloted by Carol Sugars and Douglas Rodante. * Boeing and Air New Zealand are collaborating with leading Brazilian biofuels maker Tecbio and Aquaflow Bionomic of New Zealand and other jet biofuel developers around the world. * Virgin Atlantic successfully tested a biofuel blend made from 20% babassu nuts and coconut and 80% conventional jet fuel fed to a single engine on a 747 flight from London to Amsterdam. Oil prices increased about fivefold from 2003-2008, raising fears that world petroleum production is becoming unable to keep up with demand. The near-total dependency on petroleum for aviation fuel adds extra urgency to the search for alternatives: twenty-five airlines went bust or stopped operations in the first six months of 2008 and more could fold as fuel prices soar, IATA warned . Jet biofuels in practice * Virgin Atlantic flew a Boeing 747-400 in early 2008 with one engine operating on a 20% biofuel mix of babassu oil and coconut oil * Air New Zealand will fly a Boeing 747-400 with one of four engines on a biofuel/kerosene mix in 2008/2009 * Continental Airlines will fly a Boeing 737 on 3rd generation biofuel in 2009. _________________________________________________
