A Northwest Airlines flight made an emergency landing at Buffalo Niagara International Airport Friday.
A 12-inch hole opened up in the plane's fuselage, Niagara Frontier Transportation Authority officials said.
Northwest Airlines Flight 1411 experienced a loss of cabin pressure and smoke filled the cockpit during a flight between Syracuse and Detroit, airport spokesman Doug Hartmayer said.
The airport went on alert, and the plane landed safely with 95 people aboard.
The hole in the plane's hull was found after it landed.
Eagan-based Northwest Airlines Corp. issued a statement saying it was conducting an internal review. The airline said it brought in another plane from Detroit, and the passengers arrived in Detroit from Buffalo at 6:15 p.m. Northwest said it apologized to them for the inconvenience.
