A helicopter on a sightseeing tour has crashed near the Grand Canyon in Arizona killing three people and seriously injuring several others.
The aircraft, operated by Papillon Airways, was carrying a pilot and six passengers when it came down in the Quartermaster Canyon in the late afternoon, Hualapai Nation Police Chief Francis Bradley confirmed.
Talking to media, Mr Bradley said all of the passengers were British, and that the four survivors were taken to Las Vegas’ University Medical Center, where they are in a critical condition, ABC15 Arizona reported.
Allen Kenitzer of the FAA Office of Communications said the Eurocopter EC130 "crashed under unknown circumstances in the Grand Canyon" and had "sustained substantial damage".
According to ABC15, rescue efforts had been hampered by high winds, darkness and the remote and rugged location of the accident. The pilot is apparently among the survivors.
NTSB crash reports show that Papillon Airways has been involved in numerous incidents over the past two decades, including a 2001 crash that claimed six lives.
