free fall

A rapid, uncontrolled decline, as in The markets threatened to go into free fall and we came close to outright panic. This term transfers the aeronautical meaning of a free fall, that is, "a fall through the air without any impedance, such as a parachute," to other kinds of precipitous drop. [Second half of 1900s]
