The only Cheers episode to be directed by George Wendt.
When James Burrows came down with pneumonia, George Wendt was recruited to direct this episode. It would be the only episode of "Cheers" that we would direct.
The title references the Airport series of airplane disaster movies from the 1970s. There were four in the series, though the sequels weren't numbered, they were identified by the year in which they were set: Airport (1970), Airport 1975 (1974), Airport '77 (1977) and The Concorde... Airport '79 (1979). The title would jokingly set this episode as the fifth in the series.
