This is a long shot but,

Does anyone remember a short film which was Bafta nominated (but didn't win) about two young girls who discover the wreck of a Second World War plane at the bottom of a lake?

I can't remember anything else about it other than it was within the last ten to twelve years (please don't hurt me) and I think it was a 30 min film.

But of course, I could be wrong.

Thanks in advance.
