Shawn I couldn't find any accident reports on the four CF wirestrikes I am familiar with but all landed safely thanks to the wire strike protection kits. One Kiowa, two Twin Hueys and a Griffon. As for damage - windshields cracked, OAT probes and antennas cleanly removed and all crew seat cushions needed replacing. The Kiowa was on approach, the others were in cruise. As good as the wirestrike kit is it apparently (second hand knowledge) doesn't cut barb wire strong across a valley at 1000'. It will however hold onto it nicely while the mast and rotor wind it in for you
I used to have a picture of that Twin Huey but couldn't find it for you.
I am a big fan of the wire strike protection kit after seeing it save a few friends.
