Charleston, South Carolina helicopter crash blamed on drone.

Federal authorities are investigating a helicopter crash that happened Wednesday near the southern tip of Daniel Island.

A Robinson R22 helicopter struck a tree and crash-landed Wednesday afternoon, according to Federal Aviation Administration spokesperson Kathleen Bergen.

The instructor told police he was giving a lesson to a student pilot at approximately 3:30 p.m. While the student was practicing “low impact and hover taxi maneuvers” above undeveloped land on Daniel Island, they turned and saw a white “DJI Phantom quad-copter” drone headed into their airspace, the report states.

Police say the instructor took controls of the helicopter to avoid the drone and while attempting to land, the helicopter’s tail rudder struck a small tree, causing him to lose control of the helicopter.
