The Maryland State Police helicopter is relocating from Salisbury to the Ocean City Airport for weekends during the summer. Police spokesman Greg Shipley says the Trooper 4 helicopter will be stationed at the airport in West Ocean City on Saturdays and Sundays through Labor Day. The switch will allow officials to respond more quickly to medical crises in the tourist-packed resort. The helicopter will be at the airport on weekends from 11 a.m. to 6 p.m. State police helicopter crews have also begun conducting training with the Ocean City Beach Patrol so that they can help with water rescues. In the past, state police crews handled water rescues by helicopter on their own.
