It has been conjectured that the string and unification scales may be substantially lower than previously believed, perhaps a few TeV. In scenarios of this type, orbiting detectors such as OWL or AIRWATCH can observe spectacular phenomena at trans-GZK energies. We explore measurable signatures of the hypothesis that trans-GZK air showers (``anomalous showers'') are originated by strongly interacting neutrinos. The results of a MC simulation of such air showers are described. A distinction between proton induced and ``anomalous'' showers is possible once a substantial sample of trans-GZK showers becomes available.
