An interesting aside:
in the just published (broadcasted) documentary about the 1948/9 Berlin blockade*, it is reported that in small town Celle in Lower Saxony more prostitutes were engaged than in Hamburg or Berlin: 2000 - since it was one of the main airfields for the so-called American and British "raisin bombers"/"candy bomber".
Celle, Wietzenbruch airfield, 1948
