...possibly by doing this we may make SE realise that the flying community impact is larger than they thought.
I quite agree, all aviators should stand together.
The implications of a power line very close to a gliding airfield would not only have implications for soaring points, but also for safe return to the field. Not having the ability to go around, or ensure remaining above power lines has serious implications for viability on any given day and ongoing viability if annual flying days and revenue are reduced.
