Wellington - Air New Zealand successfully conducted the world's first commercial aviation test flight powered by fuel from the seeds of the African jatropha plant on Tuesday.
Chief executive Rob Fyfe said after the jumbo jet's two-hour flight from Auckland, "It is Air New Zealand's long-term goal to become the world's most environmentally sustainable airline and we have today made further significant progress towards this."
A biofuel blend of 50-50 jatropha and Jet A1 fuel was used to power one of the airline's Boeing 747-400's Rolls-Royce engines.
Air New Zealand, which described jatropha as a sustainable second-generation biofuel, said that more than a dozen key performance tests were undertaken during the flight.
