Interestingly enough, I had a similar idea for this vessel I developed, in which the engineering section is overhead, so that the underside has room for landing gear. I was able to develop it as far as I have due to being given free reign on what my final project is for my drawing class, though I hadn't even been able to start on it besides some concept sketches by the end of November due to having other class work I had to do, and probably won't be done until the 13th, which is when it is due anyways.
