This forty-second feature is pretty scary and very impressive. Shot by pilot rickyflo_, you’ll see men climb then stand on “the clock tower,” a building in Dallas, Texas. The Dallas clock tower is a 115-foot tall ornamental spire and local landmark downtown. It’s part of the Mercantile National Bank Building, and has a clock on each side, hence the name. These daredevils climbed the tower and took a drone to prove their feat.
