This is the SC-620C, the cargo variant of the SC-620 flyer. All of these models are in the colours of the Sindusan Aerospace Corporation's Service and Repair Division. When a gravity manipulation engine has a fault the vehicle it is fitted in cannot legally fly, even if the fault is minor. Since a tow is impractical the vehicle is normally repaired where it is, so service technicians have to be equipped with tools and spare parts for the job. The parcel variant of the SC-620C is ideal for carrying the most commonly needed smaller parts, as shown. The open floor version has anchor points for strapping down larger boxes, so if larger parts are needed they can be taken to the vehicle needing repair. And finally there is one flyer carrying a complete replacement drive unit. A full replacement is rarely needed but sometimes if a repair is likely to be time consuming a replacement drive is fitted instead, and the faulty drive is taken away to be fixed to at a service centre. The more observant will notice that these vehicles actually have registration numbers that are different, though only by one digit as they are consecutive numbers. The service numbers near the front also differ, displaying "G-519", G-520" and G-521" in Galactic Standard text. I still have a mad eye for detail I guess. One more version of this flyer to prepare, which hopefully will be done before next weekend.
