Christ, that must have been some turbulence and pretty scary too.
One passenger said he heard a woman "screaming in agony" and saw another with a "gash on her head".

I’ve never experienced severe turbulence on a plane but my sister told me once that on a flight to America the plane was dropping like a stone and rising just as quick. Her seat belt held her in place but some people had head/neck injuries when they hit the overhead lockers and the flight attendants were having to hold the serving trolleys down!
