PHOENIX -- Four survivors of awere being treated at a Nevada hospital while crews tackled difficult terrain in a remote area to recover the bodies of three other people. Six British tourists and a pilot were on board the Papillon Grand Canyon Helicopters chopper when it crashed under unknown circumstances on Saturday evening on the Hualapai Nation's land near Quartermaster Canyon, by the Grand Canyon's West Rim.
A witness said he saw flames and black smoke spewing from the crash site, heard explosions and saw victims who were bleeding and badly burned. "It's just horrible," witness Teddy Fujimoto said. "And those victims - she was so badly burned. It's unimaginable, the pain."
Windy conditions, darkness and the rugged terrain made it difficult to reach the helicopter's wreckage, Hualapai Nation police Chief Francis Bradley said. Rescue crews had to fly in, walk to the crash site and use night vision goggles to find their way around, he said.
All six passengers were from the United Kingdom, the British Foreign and Commonwealth Office confirmed. Three passengers and the pilot were airlifted to a Las Vegas hospital early Sunday, Bradley told the Arizona Republic.
The survivors were identified as pilot Scott Booth, 42, and passengers Ellie Milward, 29, Jonathon Udall, 32 and Jennifer Barham, 39.
The deceased were identified as Becky Dobson, 27, Jason Hill, 32 and Stuart Hill, 30.
The National Transportation Safety Board was to begin investigating the crash's cause, Bradley said. The Federal Aviation Administration also will be investigating the crash of the Eurocopter EC130, spokesman Allen Kenitzer said.
National Weather Service meteorologists in Flagstaff and Phoenix said winds were blowing an estimated 10 mph with gusts of 20 mph around the time of the crash.
Fujimoto, a Las Vegas photographer who was doing a wedding shoot at the time of the crash, said he suddenly saw people running toward the edge of a gulch. He said he heard gasps and went to check out the commotion coming from about 600 feet below.
"In the gulch, there was a helicopter, flames, smoke," he said. "It was horrible."
He said that's when two or three small explosions went off in the wreckage and people weren't sure what to do. He said some other pilots flying helicopters in the area at the time of the crash descended into the gulch and delivered water and first aid supplies.
Fujimoto said he saw two badly injured women and one of them was yelling out a man's name. He said one of them "was pretty much burned all over."
"Her hands were bloody and body was just more burned," Fujimoto said.
The other woman, he said, was "covered in blood" and was bleeding from her head or neck.
Fujimoto said he has taken helicopter rides for photo shoots for the past few years and generally felt safe. He said the crash aftermath is the worst thing he's ever witnessed.
The tour company promised full cooperation with crash investigators and offered its sympathy.
"It is with extreme sadness we extend our heartfelt sympathy to the families involved in this accident," Papillon Group CEO Brenda Halvorson said in a statement. "Our top priority is the care and needs of our passengers and our staff."
The Nevada-based company's website says it flies roughly 600,000 passengers a year around the Grand Canyon and on other tours. It notes that it "abides by flight safety rules and regulations that substantially exceed the regulations required by the Federal Aviation Administration."
Longtime helicopter crash lawyer Gary C. Robb represented a woman badly burned in a deadly Papillion crash at the Grand Canyon in 2001. He said the company has made big improvements since that crash.
"They've improved their piloting qualifications as well as their maintenance over the last 10 years and as far as I know they've not had a crash since 2001," he said. He said flying in the Grand Canyon can be treacherous simply because of the number of helicopters there.
USA Today notes that, "Thousands of helicopters now fly over the Canyon each year, all competing for business and the same limited space.
"Everybody wants to see the same thing," the newspaper quotes Robb as saying. "It is a recipe for disaster."
"Everybody wants to see the same thing," said Gary C. Robb, a Kansas City attorney who specializes in helicopter-crash litigation. "It is a recipe for disaster."
In August 2001, a Grand Canyon tour helicopter operated by Papillon crashed and burned near Meadview, Arizona. The pilot and five passengers died. An NTSB report issued in 2004 blamed the pilot's decision to descend too fast and too close to the scenic Grand Wash Cliffs.
