Well you have met Ken "The Pouch" Cobalt in various guises, but as our Senior Formation Manoeuvre Technician he has control of all kites when they are on the ground. He has a range of outfits, similar to those of Dan the Man, another "groundie" who has responsibility primarily for the Squadron flag.

(They look like some of the pilots, but this is for security purposes only)
The Wagons are cleaned by female cleaning staff - each pilot specifies the uniform of his personal Wagon Cleaner, but all the uniforms must be flimsy!
This cleaner has her lower garment made of special cleaning material so she just rubs along the bodywork, like this! Swirls are a thing of the past with this method!
As you will see, the ground staff, apart from the cleaners, tend to wear a blue or black base to their "kit". The pilots wear black, and if you were to be in the Sector Black Stealth Flight (VERY UNLIKELY), you would get a big gun (for hazardous missions) and your uniform would be a tight-fitting pressure suit to deal with G forces and the like!
Hope that helps!
