Lightning starts with a positive fast discharge, followed by an even faster and more extensive negative discharge observed in 3D; signal polarizations slant from the discharge propagation direction and rotate between the two opposite fast discharges; these features can only be due to a cosmic-ray shower that preconditioned the discharge path and guided the discharge current direction.
