Something that baffled me recently looking at the FV-OM 01 Shimmer ( https://www.simpleplanes.com/a/xX7e7A/FV-OM-01-Shimmer ) , the plane flew lovely , and had a good speed. BUT , Taking a look at its X-ray...

(x-ray image of the shimmer here , use your imagination)

And so it was , my very understanding of SP was distorted , bent and warped to oblivion. How is it possible?? How does a plane fly so well without wings or an engine?
Update : there IS a wing in the shimmer , its just hard to spot. Has some pretty complicated xml

Thinking of making my own , it seems impossible to reverse engineer. Tips? What XML is used? Anything will help
