General aviation, hang gliding, paragliding, skydiving, balloon, and kite flying must avoid accidental contact with power lines. Nearly every kite product warns users to stay away from power lines. Deaths occur when aircraft crash into power lines. Some power lines are marked with obstruction markers, especially near air strips or over waterways that may support floatplane operations. The placement of power lines sometimes use up sites that would otherwise be used by hang gliders.<ref>[https://retasite.wordpress.com/2014/09/10/aircraft-accidents-due-to-overhead-power-lines-updated/ Aircraft Accidents Due to Overhead Power Lines]</ref><ref>{{Cite web |url=http://www.thefreelibrary.com/Pacific+Gas+and+Electric+Company+Reminds+Customers+About+Flying+Kites...-a084267973 |title=Pacific Gas and Electric Company Reminds Customers About Flying Kites Safely. |access-date=2014-10-20 |archive-date=2014-10-20 |archive-url=https://archive.today/20141020164701/http://www.thefreelibrary.com/Pacific+Gas+and+Electric+Company+Reminds+Customers+About+Flying+Kites...-a084267973 |url-status=dead }}</ref>
