A small plane crashed in the Swiss Alps, killing two people, rescue officials said Monday, according to AP. Two other people survived the Sunday crash of the single-engine Piper aircraft, which was found during an aerial search Monday by Swiss rescuers. The plane was on its way from the Italian city of Parma to Zurich when it lost contact Sunday around 7 p.m. (1700 GMT), officials said. The cause of the accident has not yet been determined. The rescue service did not immediately identify those on board the flight.
