The story
The name "Old Crows" emerged from the first use of electronic warfare in World War II to disrupt Axis communications and radars. Allied equipment and operators were known by the code name "Raven". Common jargon changed the name to "Crows" and those engaged in the profession became known as "Old Crows".
