# go ballistic

> English word · Verb

## Definitions
1. To become very angry and irrational.
2. for a usually rocket-powered, predominantly non-glide projectile or aerial vehicle, such as a ballistic missile, to travel to its target partly via unpowered ballistic or quasi-ballistic flight, usually following burnout of its rocket motor
3. for a powered, usually guided missile or other aerial vehicle to travel on an unguided or ballistic trajectory, having lost power, control or guidance

## Etymology
The idiomatic usage derives from the second-generation of jet fighters, armed with guided missiles, in the late 1950s into the 1960s, with the informal military sense of fully-powered non-ballistic missiles going ballistic when losing control and assuming a free-fall trajectory, sense 3. But in subsequent usage the term has often become associated with the intentionally ballistic, suborbital trajectories of long-range, typically nuclear-armed missiles, sense 2.
