Abstract
It is proposed that the highest energy eV cosmic ray primaries are protons, decay products of a long-lived progenitor which has propagated from typically Mpc. Such a scenario can occur in e.g. SU(15) grand unification and in some preon models, but is more generic; if true, these unusual cosmic rays provide a window into new physics.
