While spy balloons may seem like a simple technology, they can still be effective for surveillance purposes. By hovering at high altitudes, they can capture detailed images and data from a wide area. Additionally, they can be difficult to detect or track, especially if they are launched from a remote location or disguised as a weather balloon or other harmless object. However, it is worth noting that modern security measures have become increasingly advanced as well, and governments around the world are constantly developing new technologies and strategies to detect and deter potential threats, including spy balloons.
