Stuff happens. Over here a vehicle somehow drove around the fire and police vehicles on a road where an EMS helicopter had landed, and was still running. The vehicle hit the horizontal stabilizer, somehow missing the tail rotor. The pilot felt a bump, and had no clue the vehicle was approaching from the rear. The helicopter wound up being trucked back to its base for repairs. The vehicle driver said he thought the helicopter was flying very low. It was suspected that he had some ethanol in his system.
