The search for an F-16 that crashed Tuesday will continue Friday, a Hill Air Force Base spokesman said, with helicopters scouring the Great Salt Lake around Promontory Point for the jet fighter's wreckage.

The Air Force is putting together a team of investigators to probe the Tuesday morning accident in which one F-16 fighter jet crashed after its pilot ejected safely, and another F-16 was damaged but landed without incident.Air Force officials declined to comment on whether the jets, attached to the 388th Tactical Fighter Wing at Hill Air Force Base, may have collided during a routine training exercise.

"We can't confirm anything at this point because we won't know what happened until the investigation is complete," Maj. Portia McCracken said. "There are a number of possible explanations for what happened."

McCracken said investigators must examine wreckage and interview the two pilots, who escaped unscathed and apparently are the only eyewitnesses to the accident.

"They (the investigative team) can determine incredibly accurately what happened just by pieces of the wreckage, if they find the wreckage," she said.

Helicopters searched Wednesday and Thursday for signs of the crashed plane and were scheduled to resume the search Friday. The search will continue during daylight hours until the plane, believed to have gone down 25 miles west of Hill near the Great Salt Lake, is located.
