First and foremost, my deepest sympathies to the crew and families. You were out there trying to save lives. I wish a speedy and full recovery to all concerned.
Lu, Lu, Lu, Lu, …….
Your lack of understanding of aerodynamics is sometimes frightening – and this time it is definitely in that category.
You did say “At least it is a theory”. But you are wrong. It is just crap this time. Why?
1. If your theory was not crap, why didn’t the helicopter roll left, away from the slope before turning it’s nose toward the slope?
2 How did they hoist in someone before the accident without rolling away from the slope?
3. How does anyone in a helicopter rescue people from slopes?
Even if we entertain your theory for a nanosecond, why have you YET AGAIN neglected flapping to equality? Have you ever seen a ground effect diagram using a steeply sloping surface? Have you seen or heard of recirculation? Can you please attempt to explain how a helicopter tries “to maintain its' relative position to the declining ground surface” as you claim? WTF?
