The orange ‘basketballs’ seen on power lines are often a sign that you’re near an airport. High-tension wires are easy to see from the ground, but they get lost in the landscape when pilots look down at them from above. These 17lb marker balls can also be found near mountain passes, deep valleys, major freeway crossings, and airports to help prevent low-flying aircraft from hitting the power lines. Source
