Pilot killed in violent collision with Pennsylvania police helicopter

An airplane pilot died Wednesday after a violent collision with a Pennsylvania State Police helicopter near a runway at a small airport in Carlisle, about 110 miles (170 km) northwest of Philadelphia, authorities said. The FAA and NTSB said it was a midair collision, though state police did not specify whether the Cessna 150 was already airborne. The helicopter, a Bell 407 used by the police’s elite aviation unit, reportedly lost blades and its tail boom and crashed on its side. Both troopers aboard were trapped until one pilot freed the other by pushing out a window; officials said they were stable. The person who died has not been identified pending next-of-kin notification, and investigators are continuing work.
