Was on a Kuwait Airlines flight a few years ago from Bangkok to Manilla and just after they had served the meals, the aircraft

took a 200+metre vertical drop. Food, drinks, people, everything all over the cabin ... literally dripping from the deckhead/ceiling/roof of the plane. Passengers with no seat belts on went flying, some injured, staff scared .... I ended up as a passenger going round with bin bags clearing rubbish, relaxing scared passengers, because the staff were too scared. Landed in Manila to a Philippino band! lol

CNN has a report with a video.

In the video you don't see that hefty shakeups.

Just people crying and praying to Allah.

But due to these Twitter pics it was quite damaging.
