It wasn’t the entire cockpit crew of Eastern Airlines Flight 401 which was distracted. If I recall the transcript correctly, the engineer repeatedly called “too low” but was ignored by the captain, who remarked to the co-pilot “What’s the difference between a flight engineer and a duck?” The co-pilot didn’t know, so the captain provided the answer: “a duck can fly, haw haw” (sound of impact). This incident along, with similar ones, formed the basis of a documentary called “the wrong stuff” which was then used in the development of the CRM program used today.
