Two die skydiving

At 10:30 Saturday morning, a group of 20 people from Iceland who were vacationing in Florida went skydiving, Tampa Bay Online reported. Something unusual happened afterward: two of the jumpers could not be found. Authorities later found their bodies.

The victims are identified as 41-year-old instructor Orvar Arnarson and 25-year-old student Andrimar Pordarson, the Associated Press reported. They had jumped separately.

"Our helicopter was able to get a visual from the air," Pasco County Sheriff's Department spokeswoman Melanie Snow told UPI. "They were found very close to each other south of the airport off of Yonkers Road."

Authorities are not sure what happened. Arnarson was a "very experienced" instructor who had done thousands of jumps, the Tampa Bay Times reported.
