It was highly likely that the balloon was launched in Nevada, as that is where Google began their recent tests, and it might have been brought back down to earth via an attempt at “controlled descent.” The closer Project Loon returned to terra firma, it ran into the unexpected trouble of drifting into several power lines which were located in a rural part of south central Washington, resulting in a power cut to a tiny number of Pacific Power customers.
All Project Loon balloons do come with an emergency parachute that will help slow its fall from the skies as and when the situation arises, and Google has even formed a dedicated team to keep track of and recover balloons in the field. These activities have been specially coordinated with the FAA in order to make sure our skies remain safe and sound to everyone else.
