Air traffic control lost contact with the pilot of Continental Connection Flight 3407 before the plane crash landed on a house in Buffalo, New York.
This recording begins with a brief conversation between the pilot and control tower, that ends with the air traffic controller saying: "Have a good night".
He then tries to re-establish contact with the pilot, but she does not respond.
The control tower is then heard saying "apparently we have an emergency".
