This from Air Force Times: An Air Force test to see how military cargo planes perform using commercial jet fuel is going so well, the test has been extended into a second year and will expand to fighters.

The Air Force wants to learn what happens when planes use commercial "Jet A" fuel instead of the Air Force's specialized fuel, "JP-8." If the Air Force switches worldwide to Jet A, the service hopes it will save about $40 million annually.

As of December, the Air Force had pumped 140 million gallons of Jet A - about 6 percent of the service's annual fuel consumption - into planes flying out of four bases: Dover Air Force Base, Del.; Little Rock Air Force Base, Ark.; Joint Base Lewis-McChord, Wash.; and Minneapolis-St. Paul Air National Guard Station, Minn.

Air and ground crews reported no problems from Jet A, said Andre Kok, a spokesman for the Air Staff's mission support directorate at the Pentagon.

The test continues into 2011, with the goal of adding six bases by the summer and including fighters on the list of planes using Jet A. The bases have not been selected, Kok said.
