A380’s milestone flight using a liquid fuel Photo: Airbus S.A.S. 2008
February 5, 2008 The Airbus A380 has become the first commercial aircraft to complete a flight using liquid fuel processed from gas. GTL involves converting natural gas, which emits the least carbon of all the fossil fuels, to a liquid fuel oil, which can be used as a fuel substitute, or mixed with regular fuel. The three-hour flight from the UK to France was the first stage of a test flight program to evaluate the environmental impact of alternative fuels in the airline market.
