The crash of a Navy helicopter during a training flight was the second such accident in the Nevada desert in as many days and the second to kill a crew member.

The helicopter crash Thursday 25 miles east of the Naval Air Station at Fallon was not related to the search for wreckage of the FA-18 jet that crashed a day earlier 20 miles south of the base.Lt. Jonathan Bennett Nolan, 28, of Syracuse, N.Y., was killed when his jet crashed Wednesday night. Station spokeswoman Anne McMillin said the cause of the crash wasn't known.

Navy officials late Thursday confirmed that one crew member aboard the SH-60F Seahawk helicopter had died. KOLO-TV reported that the crew member died in the crash after a fire broke out in flight.

The survivors were picked up by another helicopter, treated for minor injuries and released, McMillin said.
