We were about to land at Manchester airport when this turbulence hit the plane, we were on American Airlines from JFK New York Airport going directly to Manchester airport. As soon as the video starts you can see the coke being spilled which was caused by the turbulence. The person next to me had the coke in his hand, then he spilled it in when onto my food tray. As soon as the video starts we can hear some people scream and gasp as they wasn't expecting this to happen. The ATA to Manchester airport was about 15 mins as you can also hear the captain's announcement. On the day of the landing at and around Manchester the weather was generally bad, it consisted of heavy rain and strong winds.
