  We show that a simple scaling model of very forward particle production,
consistent with accelerator and air shower data, can describe all features of
the very high-energy interactions recorded with emulsion chambers. This is
somewhat surprising after numerous claims that the same data implied large
scaling violations or new dynamics. Interestingly, we cannot describe some of
the Centauro events, suggesting that these events are anomalous independently
of their well-advertised unusual features such as the absence of neutral
secondaries.
