lung wings

If anyone is wondering what Clara is talking about when she mentions "lung wings", this is due to a bad translation (or something untranslateable).

The German word is "lungenflügel" which is in English "lung lobes". Not really sure what those are or why Clara would mention them. ("lungen" is lungs, and "flügel" is wings of course, from "fliegen", to fly).

Any German experts who can chime in with other untranslateable or mistranslated parts of the movie, please chime in. I'd also like the German screenplay (spectacular move btw).
