Some other thoughts
NVG
We've tried similar gear with limited success, some of the larger wires can be seen, if you kinow where to look, but with the reduced field of vision searching needs a lot of care.
Wire mechanical tension
On our systems (up to 33,000V) between 1/4 and 1 ton
Thinking back to the incident, as I mentioned looking up into the dark the chances of seeing the cables was very low, but by extension, if the pilot didn't know they were there - they must not have been spotted whilst landing either even with the benefit of landing lights.
Which is not intended to critisise the PIC but to demonstrate the problems
