We filled the balloon with probably too much helium, to insure enough lift to support the crash box (about 10 pounds of equipment) and overcome the irregular downdraft. Still, the balloon showed an alarming tendency to hurtle groundward as the wind changed. The balloon was also becoming transparent on one side... we wondered if it was overfull. Hoping for the best, we walked the balloon from our camp (Alien Landing Site Camp) toward the burning man. The light breeze that was rising made steering the balloon a little bit challenging.
