BROWSING through that informative organ Cathay News - the house mag of the territory's official carrier - we note that the airline, ever anxious to serve the needs of its customers, has a Flying Dictionary for new cabin crew. We reproduce below three extracts from the said dictionary and, for the benefit of readers, we also provide supplementary definitions from the first edition of our own language guide. LUNCH: A meal usually eaten during the middle of the day (or prolonged to last the whole afternoon by journalists and PR executives). WINGS: The long flat parts of an aircraft at right angles to the main body (or a pop group much loved by the thirtysomething brigade and loathed by everyone else). BOIL: To cook food in hot bubbling water (or the physical state passengers are reduced to when they hear that their flight is delayed). We should point out that the words passengers usually use in the last example have yet to find refuge in any dictionary.
