My own view about dress for the bash, black tie for gents, evening gowns for the ladies. Good God! We don't want working class people such as pilots in jeans and denim shirts, reducing the opulence of the event.
I've seen drunken pilots in the loo having problems with their ILS sheer terror. Well that's my opinion. I might attend if mummy lets me stay out late.

ps. Just a thought...I hope the naughty ladies won't take advantage of me.
