Flight path (so far) of our longest balloon flight. Over 11 months and counting. This vehicle now holds the record for the longest flying controllable vehicle in the atmosphere in human history. Also this wasn't really intentional. We pushed a design change that prevented leaks in our apex vent, and shortly after that we had a pristine balloon with no leaks and we happened to keep it in endurance stratospheric mode for awhile. It was using so little ballast that we just decide to leave it be. In a year or two from now we'll probably have hundreds of flights up there like this.

Hitting the eye is more about having lots of balloons than it is about perfect aim. This is just one manifestation of the core fact that made us start WindBorne: balloons are the ultimate high-volume, low cost, lightweight sensor delivery mechanism.
