He was about 2x hangar height and VERY close to end of runway, prop not turning and directly towards power lines

He and pax appeared to be fine and managed to get towed back.
We then looked at the wind sock and it was no budging at all, so why not take off downhill and away from power lines?
I've noticed on many occasions that we fly like sheep (not meant to be insulting). I'm sometimes so eager to get airborne I don't even look at sock, I just follow them all
