A long time ago I saw a scene from a movie where a man (a high-ranked military, IIRC) standing near a landed helicopter is decapitated by the main rotor blade. Unfortunately this was the only scene I saw, and I always thought that the movie was the third installment of The Omen series, but I recently realized that I was wrong (I saw the movie and keep waiting for the scene, with no success). Can anyone provide a reference?
Note: I am not asking about "Twilight Zone: The Movie", which is known by the death of the protagonist, Vic Morrow, during filming. The scene I am talking about is part of the movie plot.
