Whack-a-drone

In Pasadena, California, there's a cute red brick courtyard where one storefront isn't like the rest. The glass doors open onto a sparse industrial hallway, which leads to a sunlit foyer with a large spiral staircase. Go up, and you'll see a typical coworking space: open tables, healthy snacks, a collection of meeting rooms with glass walls.

Follow one hallway most of the way back, and you'll find Office 18. There are no signs of life in this tiny private office that's supposed to be the headquarters of Odyssey Robot, an upstart US drone company.
