This was the convincing experiment given by Elisha Otis in 1853, when he ordered an axeman to cut the cable holding the platform on which he was standing.
He had earlier invented an automatic brake for engines, and he adapted it to the elevator.
As a consequence of this demonstration, the early skyscrapers were able to be effective. Without it, buildings were limited to less than ten floors.
[But they also needed the invention of the structural steel frame (and later the steel reinforced concrete) to complete the skyscraper innovation.]
If the Q was a physics, rather than an engineering one, then one would soon approach terminal velocity for the circumstances.
