ANITA is an Antarctic balloon that looks downward for super-high-energy air showers. Though unconfirmed elsewhere, two ANITA events are taken seriously in the US (but not so much in Europe) as a possible source of new physics at the 10^{17} eV scale.  The events are upcoming showers at zenith angles well below the horizontal, where even high-energy neutrinos should be absorbed in the Earth. The source of excitement is that these two events, if substantiated,  definitely indicate physics beyond the Standard Model (BSM).   Validation or invalidation of the events may come from IceCube data.
I will briefly overview ANITA, then review the events' history and the history of models that attempt to explain these events.
