Eureka! Well almost, I've been browsing WW2 acronyms and abbreviations, STO was either Sea transport Officer or Station Transport Officer. The latter may well be appropriate, as plans for evacuation at RAF Stations in Germany, back in the day, were quite an imperative. Especially with US owned nukes on board. In other words, to oversee the organization of "Transport" to get various people away west smartish before the Russians arrived.
