Project Loon is Google's audacious experiment to bring the Internet to the world, ferried on the back of high-altitude balloons. A new video posted to Project Loon's Google+ page gives us a behind-the-scenes look at this radical (and, well, loony) endeavor.

Google's Project Loon balloons serve as a sort of aerial network, navigating stratospheric winds and communicating with an area's wireless provider, ground-based antennas and one another to potentially offer connectivity to anyone with a smartphone. The aim is to bring Internet access to the 2 out of 3 people in the world who aren't connected. Back in June of 2014, Project Loon successfully beamed the Internet into the classrooms of a small town in rural Brazil, marking a significant "first" for the project.

The project has come a long way since it was first announced back in June of 2013. A balloon that once took 3 to 4 days to create can now be produced in a just a few hours. Google launches these balloons with automated cranes and can now launch dozens of balloons a day. And these can stay aloft for over a hundred days -- a mission-control center has been set up to keep track of the thousands of balloons that will be maneuvering about the globe, guiding them into ideal places to maximize Internet coverage.
