As a German, this is one of the few movies where the dubbed version is just as good as the original, in parts even better.
Especially the part where they're speaking Jive, which is "translated" into a thick Bavarian dialect, including subtitles saying something completely different:

And for some reason, they translated the movie's title to "Die unglaubliche Reise in einem verrückten Flugzeug" (The Incredible Journey on a Crazy Airplane).
