Historic First Flight on Natural Gas

A commercial passenger Airbus A340 flying from London Gatwick to Doha, in the State of Qatar, made recent history. It flew for six hours on a 50-50 blend of synthetic Gas to Liquids (GTL) kerosene and conventional oil-based kerosene fuel. The flight was done to bolster Qatar's image as the "GTL capital of the world." The Qatar Science & Technology Park has been working to develop liquid fuels and other products from natural gas. Airbus predicts that by the year 2030, as much as 30% of the jet fuel used to power commercial aircraft will come from alternative sources.
