Cathy

Cathy is a dark-coloured airship that bears a slight resemblance to a helicopter and is owned by Carl. Carl himself does not fly the airship and leaves piloting duties to one of his subordinates. It is a considerably large airship, being spacious enough to contain several slaves, as well as space for at least one Hawkzile, and a large cockpit for the slave traders themselves to sit in.

Etymology
Cathy is a variant of Catherine, which means "pure" in Greek, from the Greek word "katharos".

Trivia

 * Although it is an inanimate object, Carl's crew think of it as female.
 * When Castor and Hakuren Oak visit the District 7 Hospital, the bus that transports them to the hospital looks somewhat like Cathy.
