Plane crash kills at least 1 person in upstate New York, authorities say

A plane carrying six people crashed in an open field near Copake, N.Y., Saturday, according to the Federal Aviation Administration.

At least one person was killed, Columbia County Undersheriff Jacqueline Salvatore said in a press conference Saturday afternoon but could not specify how many other passengers survived.

The plane did not hit any structures on the way down, Salvatore told reporters, and the crash site is difficult to access because of muddy conditions. It was unclear as of Saturday what had caused the plane to crash, Salvatore said.
