Well... on the one hand, exposure of incidents like this may educate pilots and help them avoid similar 'mishaps', on the the other hand, it re-enforces the myth that helicopters are dangerous and just go out of the control and crash at the drop of a hat.
I've lost count of the number of people/passengers who have asked me 'why do helicopters always crash?, aren't they dangerous? what happened to those Chelsea people/Colin McCrea etc?", it really frustrates me that the general public perceive helicopters like this.
