Once in the early 60s we all had to bail, but that was on a military plane, not commercial. I was only about half trained to jump and went out on a static line. They say my landing was perfect, but I honestly was too danred scared to take it all in.
That was the scariest.
Other than that, I was once on a plane that lost cabin pressure and was forced to make an emergency landing in Tucson, and another time had an incident where one wheel wouldn't go down on an EMB from PDX/SEA. They finally got the wheel down but it was a little disconcerting to look down and see all traffic stopped and watch the ambulances and fire truck position themselves, knowing that it was all for Your Flight. YIKES!
Other than that, nothing but a whole lot of shaking going on.
