Two people were rescued after a single-engine plane crashed into New York's Hudson River on Sunday night. 

The plane, a small Piper PA-32, was carrying only two people when it crashed in the Hudson River off Yonkers, N.Y., around 5:20 p.m. EST, according to the Associated Press

The crash was roughly four miles north of the George Washington Bridge, which connects New York City to New Jersey. 

The plane suffered an unknown mechanical failure while in the air, and the pilot was forced to make an emergency crash landing, the Daily Mail reported.

The flight departed from the Trenton-Robbinsville (N.J.) Airport.

Both passengers spent about 20 minutes in the freezing waters of the Hudson River before emergency workers could rescue them.

The two passengers, a man and a woman, were treated for hypothermia at the site and then brought to nearby Jacobi Medical Center. Both have been reported as in stable condition by NBC 4 New York.
