UK tourist dies in skydiving crash near Arizona's Grand Canyon

A 55-year-old British man visiting the United States died after a tandem skydiving jump near Grand Canyon National Park in Arizona suddenly went awry, authorities said Tuesday.

Coconino County sheriff’s officials said they were called Sunday to the Grand Canyon National Park Airport after receiving a report of two men injured after skydiving in tandem.

First responders found Christopher Swales unconscious at the scene and, despite life-saving efforts there, he later died at Flagstaff Medical Center, officials said.

The other person – an unidentified employee with the Paragon Skydiving company – suffered a broken leg.

The sheriff’s office said Swales had purchased a skydiving package and the dive was going as planned until the pair approached the landing area.

The pair were free-falling before hitting the ground, authorities said, though it was not immediately clear for how long.

The National Transportation Safety Board and the Federal Aviation Administration are investigating the incident.

Coconino County sheriff's officials said in a statement that "there are no indications that the incident is criminal in nature."
