I remember hearing about an incident that happened in the months following 9/11: On a domestic plane flight, a man started acting irrationally. He may have been confused or ill or who knows what, but the result was that his fellow passengers tackled him—and actually wound up crushing him to death under the weight of their bodies.
Did anything like this happen, or did I dream it up? (Like Skittlebrau…?)
I think you have a few things that could get conflated.
You have the pre 9/11 suffocation.
You have the post 9/11 CSI episode.
And, IIRC you have ALSO have at least one post 9/11 crazy passenger-other passengers beat the crap out him incident but he lives (though I have no specific cite for that one/those).
