A Singapore to London flight suddenly dropped 20 meters after breakfast was served, leading to chaotic scenes onboard.
Cabin crew were told to return to their seats mid-way through the meal service. 
Passengers snapped pictures of the in-flight chaos, and reported meal trays and even some people hitting the ceiling as the turbulence struck.
Coffee is served -- on the ceiling. 
Minor injuries to passengers and crew were reported by the airline.
Singapore Airlines staff were commended for the way they handled the incident, and for how quickly they got everything back in order.
You'd hardly know anything had occurred after the clean-up operation.

(CNN) -- Images taken on a recent Singapore Airlines flight might suggest passengers had become unusually ferocious in their disdain for the onboard meal.
But this was no "Bugsy Malone"-esque food-flinging fiesta.
The plane hit turbulence shortly after breakfast was served, and the result was culinary carnage.
"Singapore Airlines flight SQ308 experienced moderate to severe turbulence en route from Singapore to London on 26 May," said airline spokesman Nicholas Ionides.

"Eleven passengers and one crew member sustained minor injuries when the aircraft experienced a sudden loss of altitude and were attended to by medical personnel on arrival at Heathrow Airport."
Passengers reported coffee cups, cutlery and even a few people were thrown about the cabin as the plane lost altitude.
Alan Cross, one of the passengers who took the images you see here, told CNN: "Everything violently rocketed off all the tray tables into the ceiling. You literally felt your stomach going into your throat."
The mess was cleaned up soon after and passengers were given chocolate gifts on landing in London.
