The exact origin of this recording is not clear, but online it circulates as a meme sound built around a long aircraft engine roar and the German gut genug phrase, meaning good enough. A related clip titled Du bist gut genug uses the same wording in a more direct spoken form. On soundboards the flight version is shared for its length and intensity, letting editors sustain a joke about departing, escaping or powering up far longer than a short effect would allow, which keeps it in regular meme use.
