Never been on a flight never assumed I would be afraid of flying however that sounds horrific, so thanks for giving me a new fear of flying.
Can’t really let random stuff like that with a low injury profile bother you. You’d end up fearing and respecting escalators in that case.
Reminds me of the time the brakes gave out on the L’enfant Plaza escalator for the DC Metro after the Rally to Restore Sanity (a lot good that did). Everyone was piled on going down and it just gave up the ghost and accelerated at full speed to bring them all down in a pile.

For reference, the DC Metro is quite deep underground.
Don’t worry, some turbulence is par for the course but dangerous turbulence is pretty rare. Also 50 feet is an exaggeration, turbulence usually feels worse than it is. Plane rides are usually smoother than driving in a car, but flying can make you sensitive to lateral motion.
