The flight instructor of a plane that landed on the Hudson River in Orange County reports the plane had engine problems.

That's according to a preliminary report on the March second accident by the National Transportation Safety Board.

Flight instructor Liam Darcy says he and the student pilot were performing a touch and go landing at New York Stewart Internatonal Airport, when he noticed the problem.

When Darcy saw the oil pressure was indicating zero, he declared an emergency and asked to return to the airport.

When the engine lost total power, Darcy took controls from the student pilot.

He determined the plane, a Cessna 172-N, would not be able to reach the airport.

He then chose to land in the icy Hudson River, close to the Western shore, at the area with the most lighting.

Darcy and the student were able to get out of the plane and were able to reach shore.

The Long Island residents were treated for hypothermia.

The plane, which had flown from Long Island, suffered substantial damage.

A final report could take up to two years.
