A BBC program called "Top Gear" posted a video of a helicopter crash that occured during the filming of the South Korean version of the show.  In the show, a high performance Corvette ZR1 is racing an AH-1 Cobra helicopter.  After the Corvette beats the helicopter to the finish line, the helicoper circles back, when it crashes.  You can see TV crew running from the crash.  Amazingly, the pilot had only minor injuries.  Nobody was killed.  By the way, this ending did make it to the final version of the show that aired in South Korea.
