You’ve seen them in many places, the broadcast towers that send out the programming that we watch and listen too regularly. By law they have to have red flashing beacons to warn aircraft of their presence, and the beacons have to be in constant working order. So, what happens when a bulb goes out? It’s not like you can climb on a chair and change the bulb, unless you happen to have a 1,700 foot high chair!
If you’re afraid of heights, good luck with this one. You’ll see engineers working on the communications towers of 50,000 watt, WLS, Chicago.
