BOISE (AP) - The Federal Aviation Administration's denial of a request for expanded training airspace could harm Idaho's chances of landing F-35 Joint Strike Fighter wings, the commander of the Mountain Home Air Force Base in southern Idaho said.

Col. Ron Buckley said the FAA earlier this month denied the base's request for 29 percent more space in Idaho, Oregon and Nevada to accommodate the advanced F-35 jets, though it did increase vertical airspace.

Idaho officials predict the jets could bring a $1 billion economic boost to the state, which is competing with other states to land the F-35 fighters. Final decisions are not expected until 2011.

Gowen Field Air National Guard Base in Boise is also a possible destination for some of the jets.
