HILL AIR FORCE BASE, Utah (AP) _ An F-16 crashed on desert salt flats while practicing basic flight maneuvers and the pilot was killed, Air Force officials said.

The jet crashed Monday, but bad weather hampered the search for the wreckage and the pilot, Maj. Gregory C. Martineac, said Master Sgt. Neil Werenskjold.

The jet was discovered Tuesday in four feet of mud and water.

The plane from the 388th Fighter Wing at Hill Air Force Base went down about 65 miles west of the base. Weather was not believed to be a factor in the crash.

Martineac did not eject from the plane, said Senior Airman Sara Banda, a spokeswoman for the 388th Fighter Wing.

It was the fifth mishap this year involving six F-16s from the base but the first involving a death. One of the accidents was a two-plane collision.
