A 150-foot-long escalator suddenly stopped and reversed very fast, sending people on it for the ride of their life. Apparently, the massive escalator travels in between the fourth and eighth floors of the shopping mall that this took place. It was supposed to be in its going ‘up’ position, when it abruptly switched to ‘down’. From the looks of the video, there was quite the pile up at the bottom of the escalator. This is what you NEVER want to have happen while casually riding an escalator. Stairs anyone?
