The story I mentioned is "Done a Runner" by fantasyra, http://www.fanfiction.net/s/5898228/1/ , and has some other interesting touches. As I said, very faintly reminiscent of the trick they use there to get from Britain to the US. I'm quite enjoying the backgrounds you're using here and I'm looking forward to more.
