ANCHORAGE, Alaska — Anchorage officials say firefighting efforts to combat a wildfire that threatened homes in the Campbell Creek area were almost halted when crews spotted a drone hovering over the area.

KTUU-TV reports ( ) firefighters were able to contain the 2-acre blaze Saturday, but not without almost grounding a helicopter working to fight the flames due to a drone. Alaska Division of Forestry spokesman Tim Mowry says federal and state policy requires all aircraft to be grounded for one hour until a drone leaves the area.

Anchorage police had sent out an alert to the unidentified owner of the unmanned aerial system, telling them they were interfering with the work of firefighters.

Officials say the drone eventually left the area, allowing the firefighting response to proceed from the sky.
