I have copies of both of the German editions, including Gefect in den Wolken. (Yes, battle or combat in of among the clouds is the translation) Luftpiraten is the second books title (Sky pirates or aerial pirates) The english titles wwer as stated also. I think maybe the source mentioned could be in error. Or the author mentioned on the cover could be the translator and He was listed as author? IDK.
My Luftpiraten copy has almost had the lick from over use in translation. If anyone wishes to donate new copies...? Also, My daughter could translate the Spanish ones, so, consider this in the way of a grant proposal.
Luftpiraten, book 2 of the wings of justice book is translated through the middle of chapter 10, page 109 of 339 or so, so if things look up soon, I can return to translating and let everybody knoe when I'm done.
Grant, check PM's
