Tomas Van Houtryve was honored with the 3rd prize distinction for his drone photography story, “Blue Sky Days,” in the Contemporary Issues category of the 2015 World Press Photo Awards.

“Several thousand people have been killed by covert U.S. drone strikes since 2004. The photographer bought his own drone, mounted a camera and traveled across the United States looking for situations similar to those mentioned in strike reports from Pakistan and Yemen, including weddings, funerals, and groups of people praying or exercising. He also flew his camera over settings in which drones are used to less lethal effect, such as prisons, oil fields and the U.S.-Mexico border.”
