Passenger plane tests jet bio-fuel mix.
A passenger plane powered partly by vegetable oil has performed a two-hour test flight in New Zealand.
One engine of the Boeing 747-400 was fueled by a 50-50 mixture of jatropha oil and standard jet fuel. The test was a success, according to the BBC.
Another test flight earlier this year used a Brazilian bio-nut fuel. International authorities say they want a 10th of aviation fuel to come from biofuels by 2017.
