In an era of rising global tensions, a subculture of self-described "satellite boffins" is tracking classified military hardware from their suburban backyards. Using public orbital data, low-light security cameras, and software-defined radio, these hobbyists can spot stealth maneuvers and signal intelligence birds before official agencies acknowledge them. This episode explores the collision between scientific curiosity and operational security, the tools that make amateur surveillance possible, and why the military can't stop you from being good at trigonometry.
