Neither crew member was injured and the helicopter was not airborne when it hit the snow bank Thursday night, police said.
The crew had brought two patients involved in a traffic crash in Anne Arundel County to the hospital. Police say as the pilot applied power to begin lift off, the tail lowered several inches and hit the snow bank along the perimeter of the ground-based helipad. The crew immediately shut down the engines.
The extent of the damage will not be known until further examination. The Maryland State Police Aviation Command will investigate.
