Astro Teller, head honcho at Google's secretive research facility X, said in a statement:

"Under Mike's scrappy, entrepreneurial leadership, Loon moved from science project to viable venture, and Tom's valuable industry experience will help launch us into the commercial stage of this moonshot."

Mike Cassidy is Loon's old chief, and while he's out of the project, he'll remain with X to work on other ventures.

This isn't the first time the big G hired someone with experience running big companies in an effort to turn experimental projects into commercial endeavors. Google also signed up former Ford and Hyundai exec John Krafcik in 2015 to run its self-driving car division. It's worth noting, though, that the company lost a few of that particular team's key members, as well. They're now working for Uber and are developing the ride-sharing giant's autonomous car project.
