1986 I think and First Officer Bananas is flying a shiny 10, Brize to Bermuda (night stopping to continue somewhere not very popular) with the Sqn boss (he who will forever be associated with Phnom Penh) as his Captain. Just past top of climb Bananas sees the standby horizon (no go item) topple inverted. Quick scan out of the window to make sure that the blue is where it should be and Bananas is about to announce to the crew what a smart chap he is (being the first to notice this failure) when he feels a slap on the back of his head from very senior Flight Engineer. Bananas takes the 'hint' and shuts up.
Some hours later, Nav announces 'PNR Brize Captain' and four voices announce 'Oh, look the standby horizon has just toppled.'
Resulted in a 4 day layover if memory serves - and that is a story all on it's own!
Happy days.
