What happens in this video ?
This stupid accident could have been dramatic. On August 5th 2004, during take-off, the main rotor of this Robinson R44 chopper contacted an open hangar door, causing the helicopter to fall. The violent impact with the ground caused the skids to collapse and the main rotor to sever the tail boom. Among the 4 people onboard, one received minor injuries, and 3 were uninjured.
