A Top Gear stunt went horribly wrong when a helicopter nose-dived into the ground in the Arizona desert.
The accident happened during filming of a race for the South Korean version of the TV show.
A Corvette ZR1 supercar was racing a Bell AH1 Cobra helicopter, but when the raced finished, the pilot lost control and the helicopter plunged into the ground, just metres from a film crew.
US and Australian media reports of the incident say it happened last March. But Top Gear have only now released footage of it, which has been posted on YouTube.
The aircraft had reportedly been hovering at around 50 metres when a mechanical failure forced it to the ground.
No one was seriously injured in the crash, according to a message at the start of the YouTube video clip.
