Afraid of Heights? DO NOT WATCH THIS VIDEO
Aircraft warning lights must be maintained for collision avoidance. Watch climber Kevin Schmidt change a light bulb on the top of a 1,500 foot inactive analog broadcast tower belonging to KDLT TV located near Salem, South Dakota. I love the moment Kevin stops to take a 'selfy' from the very top. Joseph and Todd Thoren of Prairie Ariel Photography shot and edited this great video using a drone.
Another of their videos captures the demolition of a 300' cable head end tower in Jackson, MN. Built in 1953, it did not want to fall over but eventually does.
