The final test flight before the first full mission. Check out the video for some great footage from ground and onboard cameras.

Another milestone: The first airborne mission. This was a test flight and the balloon remained tied to ground tether lines. Video showing the event, complete with drone coverage!!

A big milestone: The first mission in the field. Sadly, this test was not intended to get airborne, but it was exciting to see the entire technology stack working correctly for the first time.
