Three of the victims have been identified as Randy Bever, Flight Nurse, 47, of Savannah, Mo., Chris Frakes, Flight Paramedic, 36, of Savannah, Mo. and James Freudenberg, Pilot, 34, of Rapid City, Sd.
The crash happened about 7 p.m. Friday in a field in rural Clay County. The Federal Aviation Administration said the initial information indicated that the aircraft was trying to refuel as it was heading to Liberty Hospital from a hospital in Bethany, MIssouri.
A finding that alerts other pilots.
Robert Haas is a physician at Liberty Hospital and a pilot. He questions why the pilot was needing to refuel in Mosby after taking off in Bethany.
"Obviously that was not a planned stop. I would say that was an emergency stop, critically low on fuel," said Haas.
Investigators from the National Transportation Safety Board and the FAA arrived on the scene Saturday morning to begin their investigation. They asked Donald Mayse several questions. Mayse owns the field where the helicopter crashed and called 911 after seeing the wreckage Friday evening.
"I got down there and said it don't look there are any survivors. It's a bad crash, and I found one pilot toward the tail end of the wreck and I found the other pilot ejected 30 yards out in front," said Mayse.
The NTSB and FAA are continuing to investigate the cause of the crash. They have confirmed that the pilot was trying to refuel. They have not said if that lack of fuel caused the crash.
