A Vietnam-era helicopter showcased in action movies crashed on a rural West Virginia road, killing all six people on board.
The Federal Aviation Administration (FAA) said the Bell UH-1B “Huey” aircraft crashed along Route 17 in Logan County at about 5pm on Wednesday.
Everyone on board were killed, said Ray Bryant, chief of operations for the Logan County emergency ambulance service authority.
The helicopter crashed in clear weather on a road near the local airport, he said.
“The entire cab of it was on fire,” Mr Bryant said in a phone interview on Thursday.
The crash happened during an annual reunion for helicopter enthusiasts at MARPAT Aviation in Logan.
It was scheduled to begin on Tuesday and end on Sunday, according to MARPAT’s website.
During the event, visitors could sign up to ride or fly the historic helicopter, described by organisers as one of the last of its kind still flying.
The helicopter was flown by the 114th Assault Helicopter Company, The Knights of the Sky, in Vinh Long, Vietnam, throughout much of the 1960s, according to MARPAT.
After the Huey returned to the US in 1971, the website says, it was featured in movies like Die Hard, The Rock and Under Siege: Dark Territory.
Neither reunion organisers nor MARPAT officials returned requests for a comment on Thursday.
“There was smoke so thick that you couldn’t hardly see nothing but smoke and flames,” she said by phone on Thursday.
“It was coming down the ditch line on the righthand side, and I said, ‘My God, I better turn around. It might catch this truck on fire.’ So I turned around and came back.”
The crash was near the Battle of Blair Mountain historic sites, where a deadly clash erupted a century ago as thousands of coal miners marched to unionise in West Virginia.
Bobbi Childs saw smoke and flames and got close enough to see a man who was trapped.
“I saw that there was a guy trapped, I guess the captain. I tried to get down to the door where he was at. You could see him plain as day. I tried to get to him, but the fire was too hot. I couldn’t get to him,” they told WOWK-TV.
The road was expected to remain closed for at least 24 hours. The FAA and the National Transportation Safety Board will investigate.
