Shuttle Cargo Doors Idea Thread

[cadaverific]

Lately i have noticed an increase of interest in making space shuttles in kerbal. I have also noted a distinct lack of people who try to create a shuttle cargo bay, and those that do do not generally show how their shuttle bay works. Therefore, i have created this thread as a place where people can (hopefully) share ideas/builds and help educate those that do not know how.

If you wish feel free to contribute some pictures showing your basic idea and how everything works.

I will be contributing my first working shuttle with cargo space for all to see later this evening.
