Attorneys clashed Thursday in a Utah courtroom over opposing characterizations of a fight between two commercial airline pilots in which the co-pilot allegedly threatened to shoot the captain for suggesting they divert the flight for a passenger’s medical emergency.

Former Delta Air Lines pilot Jonathan J. Dunn, 42, made his first federal court appearance Thursday in Salt Lake City after he was indicted by a grand jury on Oct. 18, 2023, and charged with interfering with a flight crew. His lawyer, John W. Huber, who was once Utah’s top federal prosecutor, tried to characterize the altercation as “a misunderstanding,” while prosecutors described it as a “grave offense.”

The heated argument had erupted in the cockpit of a 2022 flight from Atlanta to Salt Lake City, on which Dunn was the first officer, or co-pilot.
