Wow, planes are having a tough time these days.
This happens quite a lot... particularly on these kinds of routes.
A few years ago, a former co-worker of mine said that he was on a flight with a guy who had a mental breakdown and tried to get to the exits, while they were 35,000 feet above the ocean. (Of course I think those doors are pressurized such that it's impossible to open them at that altitude, so there was no danger.) I guess being on a long international flight makes some people a bit loopy.
