The internet has transformed the way the world communicates, learns, governs, and exchanges ideas, but billions of people across the globe lack reliable, affordable access. Loon was a radical approach to expanding internet connectivity. Instead of trying to extend the internet with traditional ground-based infrastructure like fiber optics cables or cell phone towers, Loon took to the sky with a network of balloons. Loon's balloons traveled along the edge of space to expand internet connectivity to rural areas, fill coverage gaps, and improve network resilience in the event of disaster.
