> the London-Singapore flight suffered a sudden drop as a meal service was under way.
Meal service is probably the single most vulnerable moment to encounter turbulence. How many of the safety-first-at-all-times brigade could dine while tightly strapped to their seat? And no matter how tightly strapped in you are, you could not avoid being splashed by scalding coffee, as some passengers on the in the report were.
Also, the flight time from London to Singapore is 13 hours and 15 minutes (non-stop). How many of you would stay tightly strapped in at all times for that long?
