As if dodging gates weren't difficult enough, skiers in the modern world also need to keep an eye out for falling drones.

Hirscher went on to finish the race second and seemed unaffected by the drone's crash, but he was less than pleased by the near miss.
"This is horrible," Hirscher told the Associated Press. "This can never happen again. This can be a serious injury."
