How exactly does fog and low visibility lead helicopter accidents so often without mid-air collision and if they are not planning a landing?

Question

I can understand how low visibility will cause a crash during landing or take off. I can also understand how it could lead to collisions with tall structures like masts and trees. However, in many of these cases it doesn’t seem like they collided with anything. They seem to drop out of the sky “due to low visibility”.

Answer 1

The fog alone is usually not a real issue.

The FIM-92 Stinger Shoulder Mounted Anti Air Missile coming out of it, much more so.
