The Germans fielded the first operational jet fighter in WWII, the me262.
This model was constructed in OpenVSP. I've learned a few more things about using the program, but still don't understand how one might round off the wingtips, nor how to properly shape the cross-sections. I used a POD object to form the canopy; it gives a smoother result than the FUSE object, but no individual cross-section control. Perhaps I'll try this same model in Sketchup.
