Not every threat is directly controlled by someone on the ground. Some are just lazily drifting about, riding the winds, rising into the skies on their own.
Of course, I’m talking about balloons. And not just party balloons either. Large balloons are used in many scientific fields, including meteorological research. An estimated 90,000 free balloons are released every year. The National Oceanic and Atmospheric Administration alone launches 102 weather balloons from sites around the United States, the Caribbean, and the Pacific.
