Can't believe that no one has mentioned "A winter flight"
http://www.imdb.com/title/tt0088407/ Sean Bean, Gary Olsen and a very young Reece Dinsdale as an Assistant Air Traffic Controller. To quote the IMDB site "There is alcohol abuse,violence,sex and birdwatching. People who have been in the RAF tell me it is very realistic picture of the RAF in the 1980s." The scene in the "Pigs" bar still makes me want to wretch.
