  It is shown using numerical simulation that classical charged tachyons have
several features normally thought to be unique to quantum mechanics. Spin-like
self-orbiting helical motions are shown to exist at discrete values for the
velocity of the tachyon in Feynman-Wheeler electrodynamics and in normal causal
electrodynamics more complex closed orbits also appear to exist. Tunneling
behavior of the classical tachyon is observed at classical turning points
depending on the angle of incidence. The equations of motion appear to be
chaotic and effectively indeterministic when the tachyon crosses its own past
light cone. It is argued that self-interacting tachyons moving in a tight helix
would behave causally, and that they could be a basis for a hidden variable
description of quantum mechanics. A procedure is proposed which could determine
the fine structure constant.
