The captain of the Delta flight accidentally locked himself in the bathroom during the flight from Asheville, North Carolina, to New York. The co-pilot became alarmed and notified air-traffic control after a passenger tried to alert the cockpit of the problem.
The conversation between the co-pilot and the control tower was recorded and posted on air traffic control website LiveATC.net.
Indianapolis-based Chautauqua Airlines said the pilot had decided to answer the call of nature about 30 minutes from landing but had become trapped.
