I have recently written a trajectory program which includes aerodynamic resistance, that is, only form drag at this point. Out of curiosity I put in some ludicrous inputs such as speeds above Mach 1 (I know that wave drag becomes significant at that speed and my calculations would be rendered inaccurate), but either way, I get my program to give a trajectory that has a shape like a sideways sigma (not the circle-like one) and that the "projectile" takes a near 90° turn downwards. My question is, can aerodynamic trajectories ever look like this (in theory, at least) or is this an artifact of shoddy programming. I do not want speculations as much as I want a clear, well supported answer. I'll try to eventually get a picture here.
