I Stand Corrected

In my review of the new Narnia movie I questioned how Susan and Peter, the elder Pevensie children, made it over to the US in the midst of World War II.  I have it on good authority that there was a wartime program of bringing children to the US to escape the Blitz.  One review I read later explained that as young adults the two had some service related jobs that brought them to the States.  Either way their transatlantic journey was not implausible as I first imagined.
