Am I missing something?
Surely we don't expect (or do we) power company's to install balls/flags on all power lines. We all know the dangers of flying LL. Markers on wires on approach / departure to air strips, yes no question (although I have none on wires in relation to my private strip).
How many have seen the wires not marked crossing the gap on the NE Highway at Murrurundi? If you hit them you are really exceeding your LL limits, but I hear of pilots that skimp over them at times.
