Your post is an example of forced rationality. You're ignoring the fact that it's not just one production. I would consider your position if there was one continuous production with small to no variations. Why are you ignoring the following? - the sounds have the length of a yell or a moan. - the silence between them is not fixed or related to any other sound that we can hear on the plane. - there are no artifacts, except the weird pitch going up artificially in one of them, which might point to a prerecorded and manipulated sound - if this was a electromechanical issue, it would have to mimic a significant part of the human anatomy, including a tongue (there are a few productions that sound like the throat is constricted and the tongue is rolling slightly). Sure, a random electromechanical issue could have these characteristics, but isn't that extremely unlikely? You would expect other noises, not just the vocal-like sound.
