So the big changes right off the bat, easy to find: the folding wings, the landing gear, the ability to actually carry cargo...

Well, the original one was always able to carry cargo. It was just set up differently, right? So now it's more like the Aurora, in the sense that it carries it from above and then drops it. Whereas the original one had sort of a... I'm not sure what to call it. It had a platform upon which you place the cargo, and then that moved up like an elevator. So actually, let me go straight to it. When we first started working on the rework, this was originally going to be a ramp sort of setup, but it didn't give us enough space to do as much cargo as we actually wanted. So we ended up just switching to more of an Aurora cargo system so that we could actually just carry more cargo. It was more efficient.
