I tend to agree with Bram. A plane is an infinitely thin, infinitely wide and
long part of 3D space. As such, it has no volume, and therefore the only way to
collide with it is to touch it (i.e. a solid can't be "inside" a plane).
Being completely "under" the ground plane is a special case that should be
handled in the application. Mathematically, there's no collision when something
is "under" (or "over", for that matter) a plane because "under" and "over" are
