EIELSON AIR FORCE BASE, Alaska -- U.S. Air Force Airman 1st Class Victoria Ortaleza, a 354th Aircraft Maintenance Squadron electronic and environmental systems journeyman, became familiar with how the F-16D Fighting Falcon operates in air as part of an initiative by her leadership to help learn the impacts of her contribution to the flying misison.
