⚑🟠 #Aviation marker balls are bright orange spheres clamped onto high-voltage power lines near #airports and #valleys.

They don’t carry #electricity or improve transmission – they simply make thin wires visible to low-flying pilots. Installed by #helicopter crews, each ball is about the size of a beach ball and lasts 10-15 years.
