PHOENIX (AP) -
Authorities say four people injured in the crash of a tour helicopter have been airlifted to a Nevada hospital and crews now are recovering the bodies of the other three people aboard who died.
Six passengers and a pilot were on board the Papillion Grand Canyon Helicopters chopper when it crashed around 5:20 p.m. Saturday on the Hualapai Nation near Quartermaster Canyon.
Hualapai Nation Police Chief Francis Bradley says the survivors all were taken to a Las Vegas hospital as of 2 a.m. Sunday.
Authorities say the four were level 1 trauma patients.
The identities and nationalities of the seven aboard weren't immediately released.
Bradley says National Transportation Safety Board officials were expected at the crash scene by Sunday afternoon to begin investigating the cause of the crash.
Authorities say a tour helicopter has crashed in the Grand Canyon, killing three people.
Hualapai Nation Police Chief Francis Bradley said six passengers and a pilot were on board the Papillion helicopter when it crashed around 5:20 p.m. The other four were injured, and were still being treated at the scene.
An after-hours phone call to aerial tour company Papillion was not immediately returned Saturday. The company's website says it flies roughly 600,000 passengers a year on Grand Canyon and other tours.
Federal Aviation Administration spokesman Allen Kenitzer said the Eurocopter EC130 crashed in unknown circumstances and sustained heavy damage.
