Well if an object is tossed into a vaccuum, and is fairly close to the 
surface of a large massive body, it's path is close to a parabola. But 
with air resistance, and curvature of the earth, the path of a falling 
body is no longer  a parabola. I doubt it is any of the simple conic 
sections. Certainly the distance between Hague and London is far enough 
for both effects to ruin any parabolic arc.
