On The Trapeze

In this image, the pilot of an F9C biplane -- the type usually carried by the airships ZRS-4 and ZRS-5 -- sits just out of the cockpit. His left arm is raised as he adjusts the strap of his flying helmet, his right arm is held just in front of him, palm down. His expression is slightly amused, or possibly tired.

An F9C pilot — apparently having just returned from patrol — signals the flight operations officer aboard ZRS-5.
