We dont use/need the wire strike warner because we don't operate at those heights for police work (Different story for HEMS). Usual score: risk management/weight/cost penalties etc.
I think you'll find this wasn't due to a wire strike anyway...
I suspect they walked away from this mainly because of the crashworthiness of the EC135. I don't think a squirrel would have coped as well. <img src="eek.gif" border="0">
