A small plane plunged into the Mohawk River in eastern New York with three people aboard, and at least two were found dead after the aircraft sank in 9 meters of water, a Federal Aviation Administration spokesman said. The Piper Cherokee went down near Scotia around 2:30 p.m. (local time) on Sunday , shortly after taking off from the nearby Mohawk Valley Airport, FAA spokesman Jim Peters said. Scotia is about 32 kilometers northwest of Albany. The third person's condition wasn't immediately known. Mr. Peters said divers were searching to see whether anyone else was aboard. A skydiving instructor at Mohawk Valley Airport said he and others who were in the small airstrip's restaurant heard the crash, ran down the airstrip and jumped into the river to help a fisherman drop an anchor to help rescuers find the downed plane. "There's nothing we wanted to do more than get into that plane," said Michael McGuire. The aircraft was registered to Kolath Airlines LLC of Bear, Delaware, Peters said. A woman who identified herself as Kolath's registered agent said she didn't know about the crash and had been unable to contact anyone with the company. FAA records show the plane, a Pennsylvania-28R-180 model, was manufactured in 1969.
