RedactedNarrative: Unit private dock in Georgia with two occupants. Unit 1 went in Choestoea Creek and stopped to swim. Operator and Occupant decided to return to the dock. Both were on Unit 1 when Operator hit the start button. Unit 1 exploded when Operator hit button. Operator and passenger were thrown up in the air. Operator landed back on Unit 1, Occupant landed in the water. The Injuries were to the left legs on both victims. As to what cut them, we can only assume it was fiberglass pieces from the explosion. The only pieces recovered were a small portion of the seat and the square storage box in the rear of the jet ski. Operator was unconscious and was on top of unit 1 which was on fire. Occupant went to unit 1 and pulled Operator off and shoved unit 1 Into the lake to get the burning vessel away from them. Occupant took off his life jacket and ripped it apart to get the foam out of the inside to use as gauze. Occupant took the straps off the life jacket and used them to hold the foam against the wounds to try to control the bleeding. Operator regained conscious after three to five minutes. Occupant then took the whistle off Operator's life jacket and started blowing it and yelling for help. Occupant and Operator took turns blowing the whistle. Another vessel on the lake saw smoke and had turned down their radio to talk about what the smoke might be from and heard the distress signal from the whistle and went in the cove to find Operator and Occupant. Good sam took them back to his dock and called 911. Operator and Occupant were transported to Oconee Memorial Hospital and treated. Operator suffered lacerations to her leg and a fractured leg. She was sent to the operating room to clean the wounds and to sew the wounds back together. Operator was held over night for observation. RIO checked on Operator on June 11,2014 and she was in good spirits and was told she could go home around noon. Occupant was treated and released from the emergency room the night of the incident.
