MEMPHIS, Tenn. (AP) _ Federal authorities said two men on a Northwest Airlink flight from Detroit to New York were arrested after one of them asked to see the cockpit and initially refused to sit down on Friday.

Neither man got into the cockpit, and it did not appear they tried to force their way in. The flight landed without incident at John F. Kennedy International Airport.

Memphis-based Pinnacle said the 50-seat regional jet was full. It operates with two pilots and a single flight attendant.

The Homeland Security Department ``is monitoring the ongoing investigation,'' spokesman Brian Roehrkasse said.

Pinnacle Airlines operates the flight under the Northwest Airlink name. Northwest Airlines uses Pinnacle as one of its regional carriers.

Pinnacle said one of the men asked to see the cockpit during the flight and was told by a flight attendant that he could not. Then, five to seven minutes before landing at JFK, the man ``repeatedly stood, despite several commands from the flight attendant to remain seated. Following proper procedures, the flight attendant informed the captain of the passenger's repeated actions,'' the statement said.

The incident happened aboard flight 3741 out of Detroit.
