Crashed plane’s engine is missing

Federal investigators say the left engine on the US Airways jetliner that made an emergency landing in the Hudson River is missing.
   
Police divers were using sonar Friday to help find the engine as investigators brought in a giant crane, divers and a barge help pull the aircraft from the river.
   
National Transportation Safety Board spokesman Peter Knudson said it’s unclear when the engine separated from the plane. He said that will likely be solved once the flight data recorder is retrieved.
   
Experts say it’s not uncommon for engines to break apart from planes after bird strikes, because of the severe vibration brought on in such incidents.
   
In a photograph of the plane as it approached the river, it appears to have both its engines.
