The English word Captain comes from Juan Tripp, president of Pan Am. Because Pan Am had a large number of seaplanes at that time, the word captain was transplanted to the plane and the first pilot in the plane was called "captain".

On civil aircraft, transport planes and bombers carrying two passengers, the captain's seat is located on the left side of the cockpit; On a fighter plane with two passengers, the captain's seat is located in front of the cockpit; On two-seat trainers and helicopter gunships, the captain's seat is located behind the cockpit.
