The chances of you being in a free-falling elevator are remarkably small, but this information might at least help alleviate any fear you have toward riding them.
As this video from the Business Insider YouTube channel explains, there have been very few incidents of elevator cables snapping. That being said, researchers at MIT decided to figure out the physics of surviving such an event, and it's not jumping right before impact. The trick is to lay down flat on the floor in the center of the car so all of your body weight will be spread out. When the car crashes into the bottom, the force will be evenly distributed, giving you a chance at surviving. Again, this will probably never happen, but now you can hop onto the elevator with a little less fear.
