"Azok fölé a hegyek fölé száll fel a repülőgép, amik mögött nem laknak emberek."

Translation: The airplane flies up above the mountains, behind which no people are living.

I'm not sure but I think the audio line is missing a word : "... szall _ a repulogep" instead of "... szall FEL a repulogep". My hearing is not the best, if someone else can confirm we can report the mistake

Yes, confirmed, "fel" is missing.
