Landing gear struts compress, so there isn't a single point of intersection. Worse, they don't always point down. Even worse, the ground isn't always flat, so a plumb bob won't always tell you the right point even for a vertical landing gear strut. Elevation is the wrong metaphor for this problem. As is being discussed on the plib list, what is really needed is a generic vector intersection test. That would clobber both the mouse click picking problem and the gear strut test in a single blow.
