The Phantom reference is from the old Estes Phantom demonstration rocket. The Estes Phantom was transparent to see the inside components of a model rocket.

For this rocket, the labeling idea came off a post on a rocketry forum where a picture of a full size jet liner was attached. Instead of the standard paint, the outside of the plane was labeled: "Pilot Inside" ,"Engine" and "Wheels below!".

I took it a step further adding some descriptions inspired by the stickers from the old GooneyBird kits. These decals say "Nerd Bird", "Wadding?" and "Pointy End Up".
