LAS VEGAS - An Air Force official says the crash of an F-15 jet in the Nevada desert during a training exercise has left one pilot dead and the other injured. Air Force spokesman Andrew Dumboski says the two-seater plane went down at about 11:30 a.m. Wednesday on the Nevada Test and Training Range outside of Goldfield, Nev. The names of the pilots were not immediately released. Dumboski says the injured pilot is in stable condition and is under observation at Mike O'Callaghan Federal Hospital. The pilots were assigned to the 65th Aggressor Squadron at Nellis Air Force Base near Las Vegas. Goldfield is about 180 miles north of the base.
