Air control towers sure look... serious. Which kind of makes sense: if it’s your job to direct the fate of hundreds of people every day, chances are you’re going to want to see an imposing-if-futuristic structure at the end of your commute. Nothing like a strong coffee and big sharp building to wake you up in the morning. The always excellent Present and Correct have put together some photos of the most striking air control towers from around the world. Worth coming back down to Earth for.
