Divers using sonar and rescue workers canvassing the woods will resume their search in the upstate New York area where a volunteer Angel Flight crashed, killing at least two people.

Town of Ephrata County Board Supervisor Todd Bradt says rescue workers will resume their efforts Sunday to find the pilot. He said divers will go into the large pond where the bulk of the plane was submerged, using sonar because the water is "so muddy and murky."

Fulton County Sheriff Thomas Lorey has said the flight's two passengers were found dead Friday near where the twin-engine plane crashed in a wooded area in Ephratah, about an hour west of Albany.

Angel Flight is a nonprofit group that arranges free air transportation for sick patients from volunteer pilots.
