ZEPHYRHILLS, Fla. (AP) - Authorities plan to review footage from a helmet camera worn by a skydiving instructor during his fatal jump in southwest Florida this week.
    
Pasco County sheriff's spokeswoman Melanie Snow said investigators will review footage from 41-year-old Orvar Arnarson's camera.
    
He and 25-year-old student Andrimar Pordarson died Saturday. The two had successfully completed two jumps earlier that day but did not return from their third. The men jumped separately, not in tandem.
    
The co-owner of the skydive facility said the men didn't deploy their main parachutes. Both men had backup automatic activation devices, but they didn't have time to fully inflate.
    
The medical examiner says the cause of death was blunt trauma. Autopsy results are pending.
    
The victims were in a skydiving group from Iceland that travels to Florida annually.
