The book was translated by Hans Herdegen. Two chapters "J9982" and "The Zone Call" remain untranslated. The reason being not very hard to guess, since in both chapters a German plays a traitorous roll. The book is translated very well, but there are still a reasonable amount of passages left out or changed. Especially those in which a bad image of the Germans was given.
For example the words "Hun" and "Boche" were left out, while Johns explains in his foreword that the word "Hun" wasn't meant to be denigrating. (this part of the foreword was also left out of the German text).
Still it remains strange that the Nazis allowed this translation. Probably the reason why was the general admiration for the chivalrous behaviour of the pilots from both sides, which is also shown in a review in the "Hannoverscher Anzeiger" from that period:
"Das buch gehört zu den echtesten Äusserungen wahren Frontgeistes. Fern von jedem falschen Pathos erleben wir atemberaubende Luftkämpfe zwischen englischen und deutschen Fliegern."
