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 La Infant Plaza escalator for the D/C 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.
