Larry Linville must have known that they'd never make Frank commanding officer of the 4077 forever... Interesting. Maybe it would have been more plausible if the plane had just crashed as opposed to being "shot down". Even in a time of war, shooting down an airliner would have made for quite the international incident... 30th Anniversary Special, I think that was. In those days, the only absentees were Linville and Stevenson...fifteen years later, Alda, Farrell, Swit, Farr and Burghoff are the only lead actors left standing.
