Title: First Tau Neutrino airshower astronomy ( and Signals?)
Abstract: PeV-EeV energy neutrino Tau may lead to a filtered and amplified upward tau Airshower Astronomy. Present and future experiment may ( already or soon) disentangle tau neutrino astronomy signals: ANITA, Grand, Poemma, Auger and other group are in rush for this peculiar neutrino horizons.
