The sound of it flying over is not consistent in terms of a normal fly-by as such. Sounds like it’s stooging around at slower than normal speed and ignoring the fact that you can’t hear any blade slap of it slowing down, it sounds like it’s slowing up and or turning slightly for around 10 seconds before the impact. Certainly doesn’t sound like a helicopter on it’s side in a 5,000ft descent rate.
