This build is for anything in a civil role that moves people or cargo, performs a service (ambulance,
firefighting, cropdusting, logging etc.) air-land-sea-space; flying, rolling, crawling, swimming, hovering
etc.
The only proviso is that the subjects are unarmed, so military transports are OK, gunships are not.
Bombers, fighters etc. converted to non-lethal use are encouraged.
Any and all media are included: physical models, digital models/art, carved soap, bread etc.
If you have a question about a specific subject being allowable, just ask.
Enjoy.
