Two helicopter pilots have walked away unscathed after their aircraft crashed into the ground while filming an episode of Top Gear.



The chopper – a retired army AH1 Cobra attack helicopter – was reportedly filming a Chevrolet Corvette for Top Gear Korea when it nosedived into the ground in Coolidge, Arizona.



Local man Steve Esparza was filming using a small camera when the accident happened, and told Fox News in Phoenix that he did not think those on board the chopper had survived.



"I think the thing that shook me up the most was, I thought the pilots were dead. I turned the camera off ... I didn't want to roll on what I thought I was about to see."



“My heart was pounding, and I knew that I was going to witness something and I just kind of – I just followed it with the camera,” Esparza says.



“When that machine takes off anyways, and you’re pretty much far away, it’s beating you up pretty good on the ground. But when it screams by you and it hits the earth, it’s undescribable (sic).”



Despite the wreckage, both pilots climbed out of the chopper and walked away unscathed. One even remembered to shut-down the engine before walking away.
