The same thing (but worse) happened some years ago to a flight near the Hawaiian islands. A stewardess got sucked out and was lost in the Pacific Ocean. No explosives involved- it was a metal fatigue issue, if I recall correctly.

They’ve had that incident recently on Manswers on the Spike channel. Supposedly, it was her last day and she wasn’t a very good stewardess.
