Hm... it seems the photographer is higher than the plane: the right side of
the plane is higher (check out the wheels). Which means that the angle
we're looking at the plane is smaller (measured against the horizontal)
than the angle we're looking at the runway. Which means that (use
trigonometry) the shadow on the runway should be wider (in the picture)
than the original object casting the shadow. Which I don't think it is.

So how come -- explained geometrically -- that the shadow on the runway is
smaller in the picture than the object casting the shadow?
