Authorities say a man from the United Kingdom has died in a skydiving crash in northern Arizona.

Coconino county sheriff’s officials identified the man on Tuesday as 55-year-old Christopher Swales.

Deputies were called on Sunday to Grand Canyon national park airport about two men injured after skydiving in tandem. Authorities said Swales was found unconscious on the ground and later died in hospital.

The other man suffered a broken leg. His name was not released.

Sheriff’s investigators said Swales went on a paid tandem jump with a skydiving company at the airport. The men had difficulties when approaching the landing area and were in free-fall before hitting the ground.

The National Transportation Safety Board is investigating.

A spokesman for the UK Foreign and Commonwealth Office spokesman confirmed that the department is supporting a British man’s family. “Our thoughts are with them at this difficult time,” he added.
