A privately-operated drone forced a helicopter to stop fighting a wildfire in Minnesota this past weekend.
The Minnesota Interagency Fire Center (MIFC) confirmed to BMTN that there was a "drone incursion" that forced the helicopter to land four miles northeast of Little Falls around 12:30 p.m. Saturday.
The drone was spotted by the pilot as he dropped liquid on the blaze below, at one point hovering above the helicopter.
The pilot safely landed while the drone, which was possibly taking images of the fire, was cleared from air space. It resumed its fire suppression measures a short time later.
The drone presented a serious safety threat to those on board the helicopter, with MIFC experts saying an object the size of a quarter has the potential to destroy a turbine engine.
"Quite simply, if recreational drone users fly their unmanned system near a wildfire, then we can’t," a spokeswoman said.
"This situation can potentially put the pilot, air crew and public at risk while increasing the threat of wildfire spread endangering lives, property and resources."
The drone operator hasn't been located, but fire officials are reminding users that it's illegal to fly drones near to firefighting aircraft.
