How many people are struck and killed by rogue blimps each year?
Over one American is being killed by a blimp every year.
I have heard of rogue elephants and rogue tigers--but elephants seem to be the main animals that are referred to as "rogue". Dictionary.com defines a rogue elephant as a vicious member who has been exiled from its herd. Though I believe that "rogue" can be used to describe other animals who have gone vicious or hostile.
