Reports are that the Chopper hit a wire pole.
HH60 are fitted with wire cutters but they apparently have trouble when dealing with multiple wires.
the wire cutter is on the upper cabin about a meter in front of the rotor mast/hub,, hitting anything like that in any aircraft is a real crapshoot,, likely your gonna cause major structural damage, in this case 7 people died... no doubt flying very low, sometimes that in and of itself is the only sin required?? sad for all, and sad for that F-18 crew,,, these things come in "clusters", just the "luck of the Irish"??
I just re-read your post, if they did indeed hit a Pole?? those wirecutters aren't gonna help with that??
some JetRangers are on skids and have a lower cutter mounted under the canopy/cabin forward lip.
