McDonnell Douglas 369E crash near Monticello, UT, United States

The pilot reported that he took off and hovered about 100 feet above the ground when the net gun, which was held by the passenger, accidentally discharged. The helicopter started to vibrate; the pilot landed the helicopter uneventfully and shut it down. Postaccident examination of the helicopter revealed the net went through one of the main rotor blades and damaged the others. There were no reported preimpact mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
